So I have this server connected to the LAN, every other computer on the LAN is fully functional. My LAN is running a domain. The DC is the DHCP and the DNS server. The DC forwards unknown or external DNS queries to the Gateway Server. The gateway server is a linux box (Untangle). It forwards all queries to the ISP DNS servers. Now on to the problem....
This server can access and be accessed by every computer on the network and even VPN clients.
This server cannot browse the internet.
This server cannot successfully ping any address outside the LAN (including the ISP Gateway address)
This server can successfully perform a nslookup on any valid web address outside of the LAN
This server is running VMWare server and all it's Virtual Machines can browse the internet.
I have tried using a different NIC, I have tried turning off enhanced security in IE7, I have tried giving it a static ip, but nothing was different
