ASA 5505 VPN - Split Tunneling
Hello All,
I am having an issue with my ASA 5505 that I hope will be an easy fix for the experts here. To begin with the VPN configured on the ASA is working beautifully. The problem is with split tunneling. If I connect with a Windows 7 machine, no problem. I am able to connect to the Exchange Server, File Servers, etc. on the remote network, AND browse the Internet on the local network. However, when I connect to the VPN with Windows XP machines, I am unable to browse locally while connected to the VPN (but I do have access to machines on the remote network). Has anyone else experienced this?
