I have a Cisco ASA 5510 using ASA v8.0(2). I have 3 of the interfaces using interial 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 - 192.168.50.0/24 network with IP 192.168.50.254

2 - 192.168.40.0/24 network with IP 192.168.40.254

3 - 10.10.10.0/24 network with IP 10.0.0.1


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

Hi


You have a choice here.

Option 1.


If you don't want to use NAT to communicate between them them turn if off using the command :-


no nat-control


Then it is just a matter of setting up ACL's to allow comms to happen.


Option 2.


If you want NAT, then you need to have ACL's and NAT statements to allow comms.

If you want option 2 then let me know how you want to do you NAT and I can give you a more specific answer with configuration examples.
