Hello all. I'm having an issue with a Cisco IPSec/VPN connection that won't seem to shake.
I connect to a 2811 Cisco router configured with the EazyVPN infrastructure, using Cisco's VPN Client for Mac OS X 10.6.1 (the latest Cisco VPN client for Mac, 4.9.01.0180). The router is running 12.4(24)T1 (using the "T" train to support SSL/VPN's) When I connect to the VPN server, all is well. But it's guaranteed that after just about 10 minutes or so, DNS queries no longer work. The VPN would still be up, and I can connect to hosts via their IP address. DNS just bums out. The workaround is to disconnect from the VPN server, and reconnect it. Of course, this isn't much of a solution, considering my IP address changes and I have re-establish some of my sessions to things. I'm seeing the same issue on my Windows XP Professional home PC as well, so I can't chalk it down to Mac. Suffice it to say, I've had this problem since I started using Mac, i.e., since Tiger. Anyone else seeing this? I'm using public IP addresses off the VPN server, so no NAT is going on. The DNS servers are sitting off the public network at the remote end of the VPN; changing them around hasn't yielded much. The problem persists whether I connect to the VPN server over UDP or TCP. All help appreciated. Cheers, Mark.
