This might be a known issue and discused before, i havent been able to find anything about it though.
i'm having issues with DDNS from clients running the Cisco VPN client against a VPN3020 software version is 4.7.xxx on both client and concentrator.
On the internal DNS server the VPN client is registered with both the ethernet adapter IP address and the VPN adapter IP address, the first one is causing problems since i'm not interested in that entry in the DNS, and it's not an IP address that i can communicate with. anyone know how to fix this issue so only the IP address provided to the VPN adapter is registered on the DNS server.
Note: IP addresses are obtained from DHCP server on the internal LAN.
