We're using a Cisco split tunnel VPN to connect to the servers necessary to do our work. On one of our new computers (Windows 7), the Cisco VPN will allow Firefox to connect while the VPN connection is running but IE8 will not work. We get an error page saying that IE cannot display that page.
When I close the VPN connection, IE is able to connect. But that means that I have to exit the software on the server, close the connection, do the work in IE8, reconnect the VPN and restart the server software.
With the split tunnel VPN, the idea is that communication should be able to continue on one of the tunnels while the VPN locks out all traffic on the other. Firefox is able to handle that but not IE.
I just want to know which program you use to establish the VPN? Cisco VPN client or Windows 7 VPN client?
If you use Windows 7 VPN client, you may check the option “Use default gateway on remote network”
Otherwise, we should try to capture the network package to further research the issue:
1) Download NetMon3.4 from the following website and install it on the computer
2) Launch NetMon3.4 on the machine.
3) In the Microsoft Network Monitor 3.4 window, click Create a new capture tab …
4) In the new tab, select all the Network Adapters in the Select Networks window.
5) Then, switch to Network Monitor, press F5 to start NetMon.
6) Try to repro this issue via Firefox and IE.
7) Go back to the NetMon window and press F7 to stop the NetMon.
8) Press Ctrl+S to save the Netmon file named test. Repro the steps above, access the folder use the shortcut and produce another log file.
9) Upload the files via SkyDrive ,and post a link here.
