I am using PPTP to secure my wireless LAN. I have two clients. One is a desktop and one is a laptop. the user for authentication for my laptop is called "laptop". My desktop works fine. My laptop drops the tunnel about every minute after opening it. I don't know the first thing about PPTP, can someone look at this section of my log and tell me what's happening?
My Wireless DMZ interface on the ASL box is 172.16.0.1
My Laptop has a static IP of 172.16.0.11
I have the PPTP set to get an address from the my LAN Network which is 192.168.5.0/24.
