Roaming Security

GTP deployments on a Palo Alto Networks firewall include roaming security.
When you deploy a firewall for Roaming security, the firewall inspects traffic that flows between roaming partner networks. The firewall is deployed between the core network in the home PLMN and the border gateway that connects to the GRX (GPRX Roaming Exchange) / IPX (Internet Packet Exchange).
When you configure GTP security for roaming, you should also configure SCTP security for roaming as described in SCTP Use Cases.
