Name Resolution over Site-to-Site VPN

I have two offices with 3 people per location.  The router at each location handles DHCP and DNS.

Site 1 has a Cisco RV320, Site 2 a Linksys RV042. Site 1 has a Synology DS713+ that the Site 2 users need access to. There's a Gateway-to-Gateway VPN configured to connect the offices for file sharing.

I can ping IP addresses at Site 1 from Site 2, but not names. Each VPN is configured to allow NetBIOS Broadcast.

Anyone know of a way I can configure these routers to resolve names?

Thanks in advance for any help you can offer.

Does that router has all entries of the local server/host details?

If the router has all host entry for your local servers, then pc's can resolve the name, If you dont have hosts details in router, then the router will forward the name entry to internet to resolve, which obviously not resolve

The router at Site 1 has an option of "DNS Local Database" so I added the host name and IP of the Synology NAS. But the router at Site 2 is older and doesn't have a DNS Local Database option.

I can suggest other options

Since you have only 3 users, you can edit the users machine host file to resolve automatically


Open the hosts file in notepad and edit like below ( you need to login to the system with admin privilege) servername or machine name file servername

Save the hosts file

try to ping the destination by using hostname from the user machine.

I'll do this. I tested it earlier today and it works fine. I just thought there might be another way, via the router's configuration.

On the Linksys router side, no option to add DNS hosts entry.

Well, I have done this with a pair of RV042s and it worked.
All that was necessary was to turn on NetBIOS traffic on both ends of the VPN settings.

This was with a peer-to-peer network which I presume is what you have.

The only "problem" is that there will end up being a single Master Browser that serves the entire pair of networks.  Now, that may not be a problem BUT NetBIOS and Windows Master Browsers only get themselves set up very slowly.  You have to wait 45 minutes for things to settle down.  It's the Master Browser computer (elected by the collection of computers from time to time) that keeps the list of computer names, etc.  

Various things can perturb that working as expected.  For example, you might not get a full complement of computers on the list depending on which computer is the Master Browser.  If you have computers with both Ethernet NIC and Wireless NIC connected to the network at the same time then there is no guarantee which interface will be working with which packets and the Master Browser function can MALfunction.  At least that's my experience with such things.  This latter problem is not unique to VPN-connected sites.  But VPN-connected sites are NOT going to be BETTER - just maybe worse.

I ended up abandoning this approach because nobody would swear it would work and some swore it would not.  I figured if I ever had trouble with it then there would be no help available!!  :-)  But, it seems to address your question.

@Fred Marshall, thanks for your comment. Very informative and helpful.

I solved this the crude way by editing the hosts file. It was affecting such a small number of computers this is OK.
