Really need your help Need help in understanding an issue faced when creating a tunnel between Asa and Sonicwall (Issue got resolved) still need help to understand.
SonicWall: Phase 1 Ikev2 Encryption aes Authentication sha256 Dh 14 Lifetime 86400 Asa: phase 1 Ikev2 Encryption aes Integrity sha256 Dh 15 Prf sha Lifetime 86400
As you can see my asa is by default configured with prf. The remote firewall sonicwall doesn't have prf on phase 1, but after changing my config of prf on asa from sha to sha256 the tunnel comes up.
Can anyone tell me if sonicwall is configured with default prf of sha256? Or else my integrity and prf should be same to match remote fw sonicwall authentication parameters As the phase 1 parameters should be same means prf is there on sonicwall otherwise the tunnel would never come up.
Optional: Palo alto also has the same authentication option so in that case also I need to keep my integrity and prf.
