We have a PIX 515E configuring EasyVPN Access. We can access our corporate network from PC's using Cisco VPN Client software, but one notebook computer using a T Mobile web'n'walk PCMCIA adapter with a SIM card cannot communicate with corporate network. This adapter working like a dial up network interface (modem), but higher speed (1.8mbps). Other internet communication are running fast, but when we logon with VPN client, the authentication is working, but after that there are no received, only sent packets in VPN Client's statistics. This PC can communicate, when I use an ADSL connection with VPN client.
Have anybody any idea why ?
