I have setup a PIX 501 for client VPN access and have successfully connected to it and can access the internal LAN. To connect I am using the Cisco VPN client (IPSec). However I am having issues where I cant connect to the VPN site from certain internet connections. From these very sites I am able to connect to other VPN sites but not this one site in particular. Can anyone offer any suggestions as to why I would be able to connect to a VPN site and not another from the same internet connection.
