I have run a config through the migration tool and I have noticed the following application generate warnings-
icmp- I understand I change this to- ping
ipsec-esp- I have no idea what this should be changed to?
gre(generic routing encapsulation)- No idea what this should be changed to?
Any help would be appreciated.
Hi @mamuhopo ,
These IP protocols need to be changed to applications. You are correct that ICMP should be changed to ping. Be aware that non-ping ICMP is now blocked but previously allowed on the ASA. The protocols ipsec-esp and gre have applications of the same names in PA. https://applipedia.paloaltonetworks.com/
Typically, these changes need to be made in the security policy in Expedition. I clone the L4 rule and create a new L7 rule with the new applications. Check out the "Replace Services by App-ID" section here -> https://live.paloaltonetworks.com/t5/expedition-articles/expedition-user-guide-v1-2/ta-p/285157#toc-....
