I have a sonicwall its IP is 192.168.30.198. I configured the X2 port for 172.16.30.1 for seperate VLAN, I plugged the X2 into a new Cisco switch and have 2 servers currently plugged in to the Cisco, the servers are set to a static IP of 172.16.30.100 and 101, I setup the default Gateway to 172.16.30.1 and the DNS servers (are also the DC's) are set to 22.214.171.124 and 126.96.36.199. The 192.168.30 network has no problems resolving by name to anything on the 192.1.1.xx network. However the 172 network can ping by IP address but cant resolve by name at all. NSLOOKUP fails as well. I know I am missing something easy, but I just cant think of it.
