if i permit traffic for inside hosts to the outside with the "ip" service, what fall under this service.
object network obj_any
nat (inside,outside) dynamic interface
object-group service DM_INLINE_SERVICE_1
service-object tcp-udp destination eq sip
access-list global_access extended permit object-group DM_INLINE_SERVICE_1 192.168.5.0 255.255.255.0 any
Do i need icmp if i have already ip within?
Solved! Go to Solution.
Firstly, it has been my experience that ICMP is not included in the "IP" service tag in cisco ASA ACLs. I usually need a separate ACL for ICMP even though technically ICMP is an IP protocol.
Secondly IP traffic does not just include TCP and UDP. Does the Cisco ACL "IP" service include GRE, ESP, AH and other IP protocols? It's not clear to me.
I'm sure I knew that when I was doing this a lot but mostly these devices just work and it's only occasionally I need to change things and then I've forgotten this.
