I have two WAN connections and one LAN connection.
FE0/0 (T1) and FE0/1 (Cable)
FE0/1/0 is LAN
I need to make sure that when Cable FE0/1 is down or track is unsuccessful that workstations (and possibly servers, read on) are able to still reach the WAN through FE0/0 (T1). I'm not sure if my NAT statement (or lack thereof) is correct.
I currently have:
ip nat inside source list 1 interface FastEthernet0/0 overload
and I tried to add:
ip nat inside source list 1 interface FastEthernet0/1 overload
for the T1, but when I add the additional ip nat statement, it replaces the other one. Do I need two NAT statements for this to be successful? How would I configure this?
Additionally I have 4 static NAT statements which are for servers to reach the WAN on their designated public IP's (if the T1 is available, we want them to go out this interface.) If the T1 is not available, is it possible to NAT them to public addresses on the Cable interface (FE0/1)?
Thanks for giving me a hand with this! Please see attached config.
