In our building A the network is 192.168.5.0 /255.255.255.0. This network connects to another building through 801q trunk (fiber). It terminates at a 3560 switch. At the 3560, the 192.168..5.x network routes to an asa5510 at 192.168.1.x and then out to the internet.
There is a seperate office in building A, that has its own 192.168.1.0 255.255.255.0 network that uses a DSL line to route to the internet
The router is provided by the carrier. The small office has 3 computers and a printer. The carrier is having DSL problems that wont be fixed for 8 days.
My plan is to pull the dsl router, insert an 1800 series cisco router and run the ethernet 0 to a spare port on the switch on the network 192.168.5.X.
ethernet 0 on the 1841 will be 192.168.5.11 and can ping the gateway 192.168.5.1 for that network. Since the internal network is 192.168.1.x, it overlaps with my primary network. The plan is to nat or PAT the 192.168.1.1 network of f0/1 to the outside network 192.168.5.x through 192.168.5.11 on f0/0 then to the internet but Im not having much luck getting the nat to work between the two interfaces. Trying to use a single 192.168.5.11 adrdess for the interface address and the NAT. Is this correct? Does anybody have any config examples? Any other suggestions?
Thanks in advance. Will post the config in the am when I can get to it.
