We have a Sonicwall TZ190 with the Lan Configured for subnet 10.20.x.x and the OPT LAN configured for 10.30.x.x network with a WAN ip of 10.10.10.4. The WAN interface is connected to a Switch with IP address 10.10.30.2. I have opened up all Ports from the WAN side to the LAN Subnets and shutdown the Content Filtering service on the TZ190.
The 10.10.x.x network is where our PIX 515e firewall is located with the inside interface set to 10.10.10.2 and it is our internet firewall. All of our PC's on the 10.10.x.x network are able to get to any web sites but our 10.20.x.x & 10.30.x.x networked PC's can only get to very few websites. The 10.10.x.x network is where our IT and admin staff are located and they can get to the 10.20 & 10.30 networks.
Everything seems to work except the problem getting to web sites. Do I need to do something on the PIX to allow the 10.20 & 10.30 network to access web sites? Also, the Sonicwall is setup with NAT enabled.
Any assistance would be greatly appreciated and never forgotten.
