I have added a WatchGuard firewall to my network. I am now using the trusted network for our SBS2011 production work (192.168.50.xx). I have an existing SBS2003 server that I need to access and have it connected to the OPTIONAL network (192.168.1.xx). When these were on two separate routers, I could browse to the SBS2003 by using the DNS name (REMOTE.MYDOMAIN.COM). Any user not connected to the WG can continue to access the SBS2003 server using the REMOTE.MYDOMAIN.COM URL. However, users on the TRUSTED network can no longer resolve this name. However, I can browse to this server by using the SBS2003 IP address (192.168.1.1).
What changes do I need to make to browse to this server by name rather than by IP address? I think a DNS entry should do the trick, but adding MYDOMAIN.COM as a new zone will impact the ability to have continued accesss to WWW.MYDOMAIN.COM (which is hosted elsewhere). An entry in each the HOSTS file on each computer on the TRUSTED network may do the trick, but that seems to defeat the "central management" capabilities of the server. Suggestions?
