Hi all.

I have configured a permanent IPsec VPN between ISA 2k4 and a Multitech Routefinder 660. Everything works fine, but after five minutes of inactivity, the VPN goes down. Re-authentication takes about two minutes and I can only re-authenticate from the LAN behind the ISA-firewall, not from the other side.

This has to be an issue on the ISA-firewall, because this is the only VPN-connection on the Routefinder with an ISA-firewall. All the other connections on the Routefinder keep working forever.

Does anyone know how to keep VPN-tunnels on ISA 2k4 alive?

Hi Linke,

Are there any entries in the Event Viewer that indicate the reason for the dropped connection? Is the ISP having problems on the ISA firewall's side?

Thanks!
Tom

There are no specific entries in the event-logs that could indicate some kind of failure and there are no problems with the ISP.
