Cisco 5505 Base with 2 x external Networks on different ranges.

Hi Guys.

I have a ISP that is providing us with 2 networks and using a cisco router.
That router is connected to a 5505 with a base license. The setup would be:
0/0 Router to firewall
0/1 Firewall to local network switch 0/1 .....
Attached to the local network I have a couple of servers that use Nat to get the ext ip address.
For some reason the NAT on the network is not working, If I try to create it, the server will loose connectivity with the outside.

If I setup a server with a static ip using the 63 network behind the firewall it wont work (without the NAT that is supposed to be handled by the ISP switch), if i plug it straight to the switch it works .

The only way I have been able to get it working was to setup a secondary 5505 with the network and connect it as follows.

ISP RoUTER -- Switch ---2 x Cisco 5505 (connected with a site to site VPN ) one of them with the 63 and the other one with the 212 network.

I have the same config working on 5510 without any problems, might it be a license issue?

Hello; On the router, you can



On the router, you can put a host route for the IP address 63.x.x.x pointing to the 212 address of the ASA? I believe that is what you are missing.


Configuration example.

ASA nat (inside,outside) source static 

On the router:

ip route (assuming 1.2 is the firewall)


That would do the trick.
