Best practice for VPN subnets

Tim asked
Last Modified: 2010-04-07
I have a network where I have about 6 people that are remote workers that connect to our network via a VPN. The VPN's are created through hardware devices Sonicwall to Sonicwall and would like to know if it would be a good idea to add the subnets that are created on the remote networks to our DNS server. Each network is a 192.168.XXX.XXX network but each has a different subnet.

If you put all devices into the same DNS domain, it is you good idea to use one DNS server for them Otherwise (different domains) you have to work with full domain names (FQDN) when accessing the other side, or with a suffix list on each client.

I recommend to use one domain and one DNS server.

You see these machines are all connecting to one domain but my question is should I list all the subnets on the DNS?

What is your interpretation of "domain"? DNS or Windows/Active Directory? If last, you have no choice, AD has to known of the subnets.

My idea of a domain is both AD and DNS working together. I have one DNS server and one AD server. Now how do you add the subnet to the AD? I know how to add them to the DNS but the AD is new to me.
