I'm having difficulty getting our client workstations connected to our Watchguard firewall. The client workstations are all running XP Pro SP2 with the Cisco VPN Client 4.6.03.0021 and are trying to connect to a Watchguard X10e-w firewall running version 10.2.3. I've looked for a document from either Cisco or Watchguard on the correct setup but haven't been able to find anything. I did find a couple of posts here that covered connecting Cisco VPN clients to 700 series Watchguard firewalls but the options are completely different.
I have this problem too.
