ASA-5510 Communicating Interfaces

Unanswered Question
Mar 13th, 2009

Ok I have a Cisco ASA 5510 using ASA v8.0(2). I have 3 of the interfaces using internal IP's for different network segments and one interface for the outside WAN. I've been reading the Cisco guides on setting static NAT between the internal interfaces to allow communication although I'm not sure I've understood it correctly so getting a little confused.

I'd like to enable the three internal interfaces to talk to each network.

1 - network with IP

2 - network with IP

3 - network with IP

i would lik to know what should we enable for communication of interface.

Points 1 and 2 are mute - traffic talking to each other on the same layer 2 domain does not require to pass thru the firewall.

Point 3 - if you have 2 IP subnets behind this interface, then I suggest you install a route, the ASA is not a router and will not act as a device to route between 2 IP subnets on the same interface.
