Configure service connections for
Prisma Access (Managed by Strata Cloud Manager)
.To configure a service connection for
Prisma Access (Managed by Strata Cloud Manager)
to allow access
to private apps or internal corporate resources, complete the following steps.- Select.ManageService ConnectionsService Connections SetupIf you're using Strata Cloud Manager, go toandWorkflowsPrisma AccessSetupService ConnectionsAdd Service Connection.
- Give the service connection a descriptiveName.
- Select thewhere your HQ or data center is located.Prisma AccessLocation
- (Optional) Enable source NAT for Mobile Users—GlobalProtect IP pool addresses, IP addresses in the Infrastructure subnet, or both.You can specify a subnet at one or more service connections that are used to NAT traffic betweenPrisma AccessGlobalProtect mobile users and private applications and resources at a data center.
- Data Traffic source NAT—Performs NAT on Mobile User IP address pool addresses so that they are not advertised to the data center, and only the subnets you specify at the service connections are advertised and routed in the data center.
- Infrastructure Traffic source NAT—Performs NAT on addresses from the Infrastructure subnet so that they are not advertised to the data center, and only those subnets you specify at the service connections are advertised and routed in the data center.
- User-ID—When selected,Prisma Accessuses this service connection for identity redistribution.User-ID Redistribution Management—Sometimes, granular controls are needed for user-ID redistribution in particularly large scale Prisma Access deployments. User-ID Redistribution Management lets you manually disable the default identity redistribution behavior for certain service connections by removing the check mark in theUser IDcolumn, and then select specific service connections to be used for identity redistribution. It's not necessary to do this for most configurations. Contact Palo Alto Networks support to activate this functionality.
- Source NAT Pool—Specify the IP address pool used to perform NAT on the mobile user IP address pool, Infrastructure subnet, or both.
- Use a private IP (RFC 1918) subnet or a suitable subnet that is routable in your routing domain.
- Make sure that the subnet does not overlap with the Mobile Users—GlobalProtect IP address pool, the Infrastructure subnet, or any other source NAT addresses used for this tenant.
- Enter a subnet between /25 and /32.
- Select anIPSec Tunnel. If you have not yet set up a primary or secondary IPSec Tunnel, selectSet Upand follow the steps below.
- Give the tunnel a descriptiveName.
- Select theBranch Device Typefor the IPSec device and the HQ or data center that you’re using to establish the tunnel withPrisma Access.
- For theBranch Device IP Address, choose to use either aStatic IPaddress that identifies the tunnel endpoint or aDynamicIP address.If you set theBranch Device IP AddresstoDynamic, you must also add the IKE ID for the HQ or data center (IKE Local Identification) or forPrisma Access(IKE Peer Identification) to enable the IPSec peers to authenticate.Because you don't have the values to use for thePrisma AccessIKE ID (IKE Peer Identification) until the service connection is fully deployed, you would typically want to set the IKE ID for the HQ or data center (IKE Local Identification) rather than thePrisma AccessIKE ID.
- Turn onTunnel Monitoring.Enter a Tunnel MonitoringDestination IPaddress on the HQ or data center network forPrisma Accessto determine whether the tunnel is up and, if your branch IPSec device uses a policy-based, enter the associatedProxy ID.The tunnel monitoring IP address you enter is automatically added to the list of branch subnetworks.
- Savethe tunnel settings.
- To add or adjust routing and Quality of Service settings, go to.ManageService ConnectionsService Connections SetupRouting and QoSIf you're using Strata Cloud Manager, go toandWorkflowsPrisma AccessSetupService ConnectionsAdd Service Connection.Set UporEdittheRoutingorQoSsettings.
- Configure static routes.
- For static routes to route traffic to and from your HQ or data center,Addthe IP subnets or IP addresses that you want to secure at the branch.If you make any changes to the IP subnets on your HQ or data center network, you must manually update the static routes.
- Configure dynamic routing.
- For dynamic routing to advertise HQ or data center subnets,Enable BGP for Dynamic Routing.
- (Optional) Select anMRAI Timervalue.BGP routing offers a timer you can use to tailor BGP routing convergence in your network called theMinimum Route Advertisement Interval (MRAI). MRAI acts to rate-limit updates on a per-destination basis, and the BGP routers wait for at least the configured MRAI time before sending an advertisement for the same prefix. A smaller number gives you faster convergence time but creates more advertisements in your network. A larger number decreases the number of advertisements that can be sent, but can also make routing convergence slower. You decide the number to put in your network for the best balance between faster routing convergence and fewer advertisements.Configure an MRAI range of between 1 and 600 seconds, with a default value of 30 seconds.
- To reduce the number of mobile user IP subnet advertisements over BGP to your customer premises equipment (CPE), specifyPrisma Accessto summarize the subnets before it advertises them by selectingSummarize Mobile User Routes before advertising.By default,Prisma Accessadvertises the mobile users IP address pools in blocks of /24 subnets; if you summarize them,Prisma Accessadvertises the pool based on the subnet you specified. For example, Prisma Access advertises a public user mobile IP pool of 10.8.0.0/20 using the /20 subnet, rather than dividing the pool into subnets of 10.8.1.0/24, 10.8.2.0/24, 10.8.3.0/24, and so on, before advertising them. Summarizing these advertisements can reduce the number of routes stored in CPE routing tables. For example, you can use IP pool summarization with cloud VPN gateways (Virtual Private Gateways (VGWs) or Transit Gateways (TGWs)) that can accept a limited number of routes.
- (Optional) to havePrisma Accessoriginate a default route advertisement for the remote network using eBGP, selectAdvertise the Default Route. Be sure that your network does not have another default route being advertised by BGP, or you could introduce routing issues in your network.
- (Optional) If you configured a secondary WAN and you need to change the peer address for the secondary (backup) BGP peer, selectUse different BGP Peer for Secondary Tunneland enter a unique Peer and, optionally, Local IP address for the secondary WAN.
- To add a community for service connections) to the outbound prefixes from the eBGP peers at the customer premises equipment (CPE), setAdd no-export communitytoEnabled Out. This capability isDisabledby default.
- (Optional) SelectDo Not Export Routesto preventPrisma Accessfrom forwarding routes into the HQ or data center.By default,Prisma Accessadvertises all BGP routing information, including local routes and all prefixes it receives from other service connections, remote networks, and mobile user subnets. Select this check box to preventPrisma Accessfrom sending any BGP advertisements, but still use the BGP information it receives to learn routes from other BGP neighbors.BecausePrisma Accessdoes not send BGP advertisements, if you select this option you must configure static routes on your on-premises equipment to establish routes back to Prisma Access.
- Enter thePeer IP Addressassigned as the Router ID of the eBGP router on the HQ or data center network.
- Enter thePeer AS, the autonomous system (AS) for your network.Use and RFC 6996-compliant BGP Private AS number.
- Enter theLocal IP AddressthatPrisma Accessuses as its Local IP address for BGP.A local address is only required if your HQ or data center device requires it for BGP peering to be successful. Make sure the address you specify does not conflict or overlap with IP addresses in the infrastructure subnet or subnets in the remote network.
- Enter aSecretpassword to authenticate BGP peer communications.
- SelectConfirm Secret.
- (Optional) Configure QoS.To start, add a QoS Profile to define the QoS classes that will shape traffic between the HQ or data center andPrisma Access. You’ll then create a QoS policy rule and add the profile to the rule, to enforce QoS on matching HQ or data center traffic.
- Enter a name for yourQoS Profile.
- SelectCreate New.
- Set the maximum throughput (in Mbps) for traffic leaving the HQ or data center service connection as theEgress Max.You can specify a value up to the maximum licensed bandwidth of your HQ or data center.
- Set the guaranteed bandwidth as theEgress Guaranteed(in Mbps).Any traffic that exceeds the Egress Guaranteed value is best effort but not guaranteed. Any bandwidth that is guaranteed but unused remains available to all traffic.
- Define each QoSClassand attach it to a policy rule.A QoS class determines the priority and bandwidth for traffic matching a QoS policy rule. There are up to eight definable QoS classes in a single QoS Profile. Unless otherwise configured, traffic that does not match a QoS class is assigned a class of 4.
- Configure thePriorityof a QoS Class.Priorities include real-time, high, medium, or low.
- Configure theEgress Maxvalue.The egress max value for a QoS class, or the combined egress max values for multiple QoS classes, must not exceed the egress max value for the QoS Profile.
- Configure theEgress Guaranteedvalue.The guaranteed bandwidth assigned to the QoS class isn't reserved for that class; unused bandwidth remains available to all traffic. Any class traffic that exceeds the egress-guaranteed value is best effort but not guaranteed.
More IKE Options
Based on the IPSec device type you selected,
Prisma Access
provides a recommended
set of ciphers and a key lifetime for the IKE Phase 1 key exchange process
between the device at your HQ/DC and Prisma Access
. You can use the recommended
settings, or customize the settings as needed for your environment.- Select anIKE Protocol Versionfor your IPSec device andPrisma Accessto use for IKE negotiation.If you selectIKEv1 Only Mode,Prisma Accesscan use only the IKEv1 protocol for the negotiation. If you selectIKEv2 Only Mode,Prisma Accesscan use only the IKEv2 protocol for the negotiation. If you selectIKEv2 Preferred Mode,Prisma Accessuses the IKEv2 protocol only if your IPSec device also supports IKEv2. If your IPSec device does not support IKEv2,Prisma Accessfalls back to using the IKEv1 protocol.
- Add anIKEv1 Crypto Profileto customize the IKE crypto settings that define the encryption and authentication algorithms used for the key exchange process in IKE Phase 1.Prisma Accessautomatically uses a default IKE Crypto profile based on theBranch Device Typethat’s being used to establish this tunnel.
- Encryption—Specify the encryption algorithm used in the IKE SA negotiation.Prisma Accesssupports the following encryption algorithms: 3des (168 bits), aes-128-cbc (128 bits), aes-192-cbc (192 bits), aes-256-cbc (256 bits), and DES (56 bits). You can also select null (no encryption).
- Authentication—Specify the authentication algorithm used in the IKE SA negotiation.Prisma Accesssupports the following authentication algorithms: sha1 (160 bits), sha256 (256 bits), sha384 (384 bits), sha512 (512 bits), and md5 (128 bits). You can also select null (no authentication).
- DH Group—Specify the Diffie-Hellman (DH) groups used to generate symmetrical keys for IKE in the IKE SA negotiation. The Diffie-Hellman algorithm uses the private key of one party and the public key of the other to create a shared secret, which is an encrypted key that both VPN tunnel peers share.Prisma Accesssupports the following DH groups: Group 1 (768 bits), Group 2 (1,024 bits—default), Group 5 (1,536 bits), Group 14 (2,048 bits), Group 19 (256-bit elliptic curve group), and Group 20 (384-bit elliptic curve group). For the strongest security, select the group with the highest number.
- Lifetime—Specify the unit and amount of time for which the IKE Phase 1 key is valid (default is 8 hours). For IKEv1, the security association (SA) isn't actively re-keyed before the key lifetime expires. The IKEv1 Phase 1 re-key triggers only when the SA expires. For IKEv2, the SA must be re-keyed before the key lifetime expires. If the SA isn't re-keyed upon expiration, the SA must begin a new Phase 1 key.
- IKEv2 Authentication Multiple—Specify the value that is multiplied by the key lifetime to determine the authentication count (range is 0-50; default is 0). The authentication count is the number of times that the security processing node can perform IKEv2 IKE SA re-key before it must start over with IKEv2 reauthentication. The default value of 0 disables the reauthentication feature.
- EnableIKE Passive Modeso thatPrisma Accessonly response to IKE connections and does not initiate them.
- IKE NAT Traversalis turned on by default.This means that UDP encapsulation is used on IKE and UDP protocols, enabling them to pass-through network address translation (NAT) devices that are between the IPSec VPN tunnel endpoints.
More IPSec Options
Based on the IPSec device type you selected,
Prisma Access
provides a recommended
set of IPSec protocol and key lifetime settings to secure data within the IPSec
tunnel between your IPSec device and Prisma Access
in IKE Phase 2 for the
security association (SA). You can use the recommended settings, or customize
the settings as needed for your environment.- Customize theIPSec Crypto Profileto define how data is secured within the tunnel when Auto Key IKE automatically generates keys for the IKE SAs during IKE Phase 2.Prisma Accessautomatically configures a default IPSec Crypto profile based on theBranch Device Typevendor. You can either use the default profile or create a custom profile.
- IPSec Protocol—Secure the data that traverses the VPN tunnel. The Encapsulating Security Payload (ESP) protocol encrypts the data, authenticates the source, and verifies the data integrity. The Authentication Header (AH) protocol authenticates the source and verifies the data integrity.If you useESPas the IPSec protocol, also specify theEncryptionalgorithm used in the IPSec SA negotiation.Prisma Accesssupports the following encryption algorithms: aes-256-gcm (256 bits), aes-256-cbc (256 bits), aes-192-cbc (192 bits), aes-128-gcm (128 bits), aes-128-cbc (128 bits), 3des (168 bits), and DES (56 bits). You can also select null (no encryption).
- Authentication—Specify the authentication algorithm used in the IPSec SA negotiation.Prisma Accesssupports the following authentication algorithms: sha1 (160 bits), sha256 (256 bits), sha384 (384 bits), sha512 (512 bits), and md5 (128 bits). If you set the IPSec Protocol to ESP, you can also select none (no authentication).
- DH Group—Specify the Diffie-Hellman (DH) groups for IKE in the IPSec security association (SA) negotiation.Prisma Accesssupports the following DH groups: Group 1 (768 bits), Group 2 (1,024 bits—default), Group 5 (1,536 bits), Group 14 (2,048 bits), Group 19 (256-bit elliptic curve group), and Group 20 (384-bit elliptic curve group). For the strongest security, select the group with the highest number. If you don’t want to renew the key thatPrisma Accesscreates during IKE phase 1, selectno-pfs(no perfect forward secrecy). If you select this option,Prisma Accessreuses the current key for the IPSec SA negotiation.
- Lifetime—Specify the unit and amount of time during which the negotiated key is valid (default is 1 hour).
- Lifesize—Specify the unit and amount of data that the key can use for encryption.
