Using Cisco Secure Client Ver 3.6, terminating on a PIX 515 firewall, remote clients using analogue BT lines, NTL broadband are able to connect to all network as configured over a VPN connection. However, BT ADSL users are having problems. These users connects fine with the VPN client icon showing in the taskbar. The issue is that there is no IP connectivity at all from BT ADSL users.
Routes have been double checked and the fact that other users using other access methods are able to connect to all parts of the network nullifies routing as an issue as specified in IPSEC debugging document by Cisco.
I look forward to your insight on this one.
