We've configured an ASA with simple architecture (PC - ASA - PC).
- We've configured interfaces and ACL permitting IP traffic.
PCs in inside and outside interface cannot ping each other.
We specified a STATIC (inside,outside) real_add_inside real_add_inside.
PCs in inside and outside interface can ping each other after adding this configuration.
We removed static configuration and the ASA is only configured with IP adress in each interface and ACL which permit all ip traffic.
After clearing xlate and rebooting ASA, PCs on inside and outside can always ping each other (as if removing the static configuration doesn't have impact on the connectivity between inside and outside).
We'd like to know if it is normal, if it is not necessary to configure NAT or STATIC to let inside and outside to communicate on ASA.
If so, what could be the reason ping doesn't work after first configuration.
