We have several thousand users throughout the USA, with various cable/dsl providers, who have no difficulty in using their VPN client.
We use the VPN 5000 concentrator, with the most updated vpn client.
We use NAT and have tried ports 80 and 8000.
Only 5-users cannot connect in Pennsylvania
We have only 5 users, who all have Armstrong cable in Pennsylvania, that cannot connect through their vpn.
Ports are not blocked per Armstrong.
Please, can any one help!!!!!!!!1
