DNS resolution between the local network and a site to site vpn network.

I have a local network 192.168.2.0/24 and a site to site VPN network 192.168.1.0/24. Both windows networks. I need to get name resolution in the local network to access the VPN network. I tried adding host file entries but that did not work. I have a dns server on the local side but have not been able to get the VPN' side's server name to resolve from the local side. Sny one have any ideas?

I took a look at the WRV200 user guide and could not find any reference that it could handle VPN DNS pass-through. This might be the main reason this isn't working.

WRV200 Firmware 1.0.32.2 Release Note -- 5/02/2007
IPSec tunnels do not pass NetBIOS broadcast packets.

NOTE: The Linksys RV082 has the DNS pass-through capability as I use it to hook up via VPN tunnels to at a lot of client locations to access their internal DNS servers as if I was locally found on the remote network. If wireless is a necessity, you could setup the RV082 as the VPN tunnel configuration and hook the WRV200 into it as an access point (AP).

If you have a DNS server on each end, and if the two sites are NOT on the same domain, you can use conditional forwarding to resolve names.  On Site A's DNS server, add a forwarder on your DNS server and specify that it is for Site B's domain only, then specify the IP address of Site B's DNS server.  Then do the same at the other end, adding Site A's DNS server to Site B's as a forwarder for Site A's domain.

If you need more specific instructions on how to do this, post back and I'll give you the step-by-step.

Will You Be GDPR Compliant by 5/28/2018?

GDPR? That's a regulation for the European Union. But, if you collect data from customers or employees within the EU, then you need to know about GDPR and make sure your organization is compliant by May 2018. Check out our preparation checklist to make sure you're on track today!

Another thing you want to make sure is enabled is NetBIOS on the server's NIC as well as the client NICs. Also some VPN routers are able to do NetBIOS pass-through. See if your VPN tunnels have this enabled.

VPN back up. My immediate problem is solved by adding a line in the host file fo the servers. I added site b's dns address as a forwarder but that did not solve the problem. Site A still could not reach site B by host name. Do I need to add records to B's DNS? I cannot configure site B until tomorrow morning. I must resolve this issue tomorrow. Any more suggestions?

A couple of questions so we can get a better idea of your layout...

1) What kind of hardware/software do you have in place for the VPN tunnel?
2) I noticed in the Zones portion, are you also using ISA as well?
3) Are you running a DC/DNS on both sides?

DNS on office side. Trying to set up simple DNS program on remote side bt not having much success.

No ISA.

Linksys wvr200 on remote side, Cisco 2800 router on office side.

Adding A records on office DNS solved the problem on that side. Cannot get Simple  DNS working on remote side.
