I am looking at an ASA 5505 ASA Ver 8.2 and anyconnect client is not being used. They have some 3rd party client that connects to port 500. However I am at a loss here as to how this was setup. I searched the cofig for VPNGP and output of command is also below but I can't ssem to figure out where in the ASA this previous person configured this to support this 3rd party VPN. In the remote vpn connection profile the VPNGP profile exists but is not selected and I dont see any such tunnel group called VPNGP as shown in users session output. Only Tunnels I know of whould be in site to site VPN and this is a remote user session using 3rd party VPN somehow. I see within the ASA there is section for IPSEC IKE1 connection profiles where the below VPNGP group policy is available for the outside , inside and a backup interface on this particular ASA so I assume this is where the support for non anyconnect client VPN was setup. I dont however see anything related to port 500 or how the VPN comes in from the outside interface of the ASA.
