Hopefully I can explain clearly what I am attempting to achieve.
We are attempting to set up a test bench connected to our network via a 2621 router.
We have connected eth0/0 to our existing network and eth0/1 to our test network.
We have assigned eth0/0 a valid existing address of 22.214.171.124 and subnet mask of 255.255.255.128 from our existing network.
We have assigned eth0/1 a private IP address of 192.168.1.1 and mask of 255.255.255.0 and it is directly connected to a Cisco 2900 switch.
We have assigned the switch an IP address of 192.168.1.2.
When we connect a workstation to the switch on the test network and assign it an address of 192.168.1.3 we are able to ping 192.168.1.2 (Switch), 192.168.1.1 (eth0/1 on router) and 126.96.36.199 (eth0/0 on router).
We are unable to ping anything else on our existing network.
What we want to achieve is to be able to to NAT translation and get access to the Internet via a workstation connected to the switch on the test network, but we can not do that.
We can't ping beyond the eht0/0 port on the router.
I think what I am trying to do is set up NAT translation and then a bridge or route between the eth0/0 and eth0/1 interfaces. Is there a way to achieve what I am attempting?
We are not using the Serial port on the router.
