I just upgraded to 2.2.0 on my Mac Pro (8x2.8Ghz 32GB RAM) and NAT seems to have ceased working. I saw the trouble ticket in the Windows forum, however, this is different. I am able to receive an IP address through DHCP, however, the NAT engine isn't rewriting and forwarding my traffic as it should. In other words, although I receive an IP address and default gateway, I still have no connectivity.
Any suggestions?
***Update*** Please ignore this. It was a DNS issue.
