When connected to our office server via vpn the machine connects but then after a while (varies between 1 an 6 mins) the vpn status says connected but i can no longer ping the server or connect to any other device's on the office network. any ideas? --- server is a dell running windows server 2003 and the client is an alienware m17x with windows 7 ultimate sitting behind draytek 2820n Routers at each location.

    That sounds like a ARP issue. The IP address pool might not be unique, and so is the IP address given by the server for the VPN client. I would first check for that.

    As Qlemo indicated it might be an issue, however tell us what the event logs say for starters on client and server

    I'm guessing your VPN server is behind nat... find some sort of keepalive setting in your router's nat table and enable it, or, establish static PAT translations that are not doing connection inspection.
