DNS between site to site tunnel

I have a site to site tunnel with a remote office. Remote end is an ASA 5510 and the coporate end is PIX with version 7.2.1(4). The remote end needs to be able to use its ISP provided DNS server for all their traffic headed toward the Internet, but when they use resources at the corporate end of the tunnel, they need to use corporate DNS servers, or at least be able to resolve names of coporate resources. Is there a way to make this work?

thank you,

Bill

disregard. It looks like my understanding of backup DNS servers was wrong. I can make this work by using a primary DNS server of the ISP, and a backup DNS server from the coporate domain.

Re: DNS between site to site tunnel

Hello,

A question; is the corporate DNS server?s IP part of the LAN-to-LAN segment!! If yes theoretically speaking, you can configure one of your local machines with secondary DNS as the corporate DNS.

Kindly give it a try and come back with the feedback..

Regards,

Belal
