VPN to SBS2003 goes "dead" after about 20 mins
Posted on 2009-12-21
I've got a VPN set up to a site I support. I tend to find that after about 20-30 minutes of being connected on the VPN, it seems to "die". The VPN connection remains connected, but I am no longer able to reach anything on the remote site - my RDP session closes and refuses to reconnect, and remote resources become unavailable.
I can work around this by disconnecting and reconnecting the VPN, then it works fine again - for about another 20-30 minutes.
I'm using XP SP3, the remote server is running Windows SBS 2003 premium. the VPN is configured in SBS 2003 using the routing and remote access wizard, the appropriate ports are open and forwarded on the network router, and i'm connecting from XP using the standard windows VPN connection.
