I've got a question about static mappings on a PIX515E running OS 6.3(5).
There are two inside LANs attached to the PIX each of which have a static mapping to the outside interface for the whole subnet.
eg static (inside,outside) 10.10.10.0 10.10.10.0 netmask 255.255.255.0
In addition, because access to a couple of servers on the internal LANS is required i've allocated these a public address:
eg static (inside,outside) 220.127.116.11 10.10.10.10 netmask 255.255.255.255
I took it that the more specific static entry (for the public address) would override the static mapping that already exists for the whole LAN.
Is this the case? When connecting from the outside inbound the xlate entry is created because the destination address is the public IP. However connnections initiated from the inside are translated to the 10. address rather than the public IP.
This is not a problem as the setup is designed for external connections in. However I am curious about this behaviour - is the order of the static statements in the config important?
This has been bugging me an a couple of colleagues for a while - would be v grateful for any ideas?!
