Network > Network Profiles > GlobalProtect IPSec Crypto

Use the GlobalProtect IPSec Crypto Profiles page to specify algorithms for authentication and encryption in VPN tunnels between a GlobalProtect gateway and clients. The order in which you add algorithms is the order in which the firewall applies them, and can affect tunnel security and performance. To change the order, select an algorithm and Move Up or Move Down.
For VPN tunnels between GlobalProtect gateways and satellites (firewalls), see Network > Network Profiles > IPSec Crypto.
