VPN working, accessing DNS server other side of VPN

Unanswered Question
Sep 12th, 2008

Attached are latest configs for each side. The IPSEC VPN is working between locations. 1841 router is HQ and has a Windows Small Business Server that hosts MS Exchange & DNS for the domain. Remote site (PIX) need to access servers at HQ by name, workstations have their DNS pointed to, but get no DNS replies from that server. Something is not properly crossing the VPN, or some ACL is blocking. From remote (PIX) side I can ping HQ devices by IP number but not by name. Nor can I access for OWA. Something not routing properly.

Please advise.

I have this problem too.

Hi Brian,

Do the following on the router:

access-list 130 deny ip

access-list 130 permit ip any

route-map nonat permit 10

match ip address 130

no ip nat inside source static

ip nat inside source static route-map nonat

clear translations : clear ip nat translations *

Check and post results If DNS is working for private ip address
