Hello all,
We have a software ipsec connection that will be between an inside server and a server in the cloud. The PA will just be a pass through so to speak, (nating and security rule).
The ipsec requires UDP 500 and 4500 and the IP 50 protocol. Do you know which app-id's I'll need for that?
The palo has these 4 app-id's:
ike tcp/500, udp/500
ipsec-ah - nothing
ipsec-esp - nothing
ipsec-esp-udp - udp/4500, udp/4501
I don't see anything for IP 50, is there?
Also, since I'm using app-id, do I leave the service still as "application-default"?
Thanks.

esp is protocol 50. If you look at the details of ipsec-esp, you'll see the 50 defined.
All protocols have a number. For example, tcp is 6 and udp is 17.
If you select the ipsec application, it should be fine to leave as application-default.

The file /etc/protocols on a Linux system has (among others) the following lines:
esp 50 IPSEC-ESP # Encap Security Payload [RFC2406]
ah 51 IPSEC-AH # Authentication Header [RFC2402]
My experience is that ipsec-{esp,ah} matches ip protocols 50 and 51
