Using a router for both Internet and branch office WAN
I have one 2610 router at each of my two offices. These routers are connected to Internet . Both the routers have additional serial and ISDN BRI WAN ports. I want to use these ports to connect the two offices.
I was told that the router connected to the internet cannot be used for private WAN. Is this true?
If this is possible please help me by giving configuration required :
1) what to NAT and what not to NAT
2) The interface used for private WAN should be defined as an inside interface or an outside interface.

Nope--it's not true. The configuration will be a little more complex, but it is possible. What is most likely to be the easiest way to handle this is to set up the defaults towards the internet on both routers (which I assume you already have), then use route maps with extended access lists to set up the nat translation pools. For instance:
On both routers, create your nat pool, then:
ip nat inside source route-map foo pool
route-map foo permit 10
match ip address 101
access-list 101 deny ip any 10.0.0.0 0.255.255.255
access-list 101 permit ip any any
This should weed out the traffic destined to the other site from being nat'd. You could also match on the outbound serial interface towards the internet on both routers, or (negative) match on the bri towards the other site.
This should get you enough to build something that works out of it.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
