I'm unable to resolve DNS names over an established IPSEC tunnel, this happens intermittently, upon tunnel establishment or in the middle of an established session.
I would simply loose access to my DNS servers and the entire remote network.
other clients on the remote network access the same DNS servers and never experience the issue.
Although we have a separate Segment for all remote access connections in the DMZ,the IPs are assigned from a cisco ACS server located on the internal network and behind a PIX 525 firewall, and this works fine.
i have checked through all the rules to see if anything has changed without luck. more baffling is the erratic nature of this issue.
any ideas are welcome..
