Hi there, I have a Cisco PIX515E server, and users are using Cicso VPN client version4.x or 5.x. This system has been working fine. But I suddenly got one weird problem on one user's laptop ... This is an IBM/Lenovo ThinkPad laptop with Windows XP Pro. Once I installed the Cisco VPN client, I could NOT access any web sites (either on Internet or inside the corporate network) over http using any web browser (either IE or Firefox). But I could access https, or ftp, or any other port (e.g. which means only accessing port 80 becomes disabled. But as long as I get the VPN connected, I can access everything. Once I uninstall the VPN client, it is back to normal.
Any idea would be appreciated, Ross
