bridge across Point to Point T1

[charlespeechumuthu]

Hello,
Our dept network is accessing Internet behind a NAT router.We have an exchange server also. Now our dept is being split for lack of space and moving few blocks away.
People moving will need access to exchange server (on private IP) and Internet via NAT router at existing facility, we have a PTP T1 running between new facility and existing facility and have two 2620 with T1 cards.
What will be the best way to configure the 2620 ? Bridging or IRB or IP routing with helper address ?. Any one can give us a skeleton/sample configuration ?
I beleive the NAT router can only do ONE class C NATing !

thanks
charles

How many people are at each location?

After reloacation, old facility will have about 22 people and new one around 20 people

Split the subnet to two halves. The config might look something like this.

int e 0
ip address 192.168.1.1 255.255.255.128
