[vpn-help] 2.1.5 -> 2.1.6b10 -- Connection silently dies after 5minutes

[kevin shrew-vpn]

Are you on wireless?  I get "silent death" problems on Windows XP all the time when the wireless network connection re-associates.  Our wireless is both a and g and Windows seems to like flipping back and forth between them.  It also seems to have a very short dhcp lease time which may contribute.

This is an old problem that plagues my Win7-64 machine with all client versions, but doesn't seem to even affect my Ubuntu machine (or any coworkers' machines for that matter).
 

I'll successfully connect to the gateway, ping inside the network, and all is happy. After about five minutes, the connection will silently fail and pings will time out. According to the "Network" tab, it is still established, and the trace utility doesn't show anything but a bunch of keep-alives for phase 1: 

 
10/07/07 08:53:59 DB : phase1 found
10/07/07 08:53:59 -> : send NAT-T:KEEP-ALIVE packet 192.168.2.101:4500 <http://192.168.2.101:4500>  -> 98.101.134.218:4500 <http://98.101.134.218:4500> 


Also the "VPN Connection Status" on the Netgear admin page lists it as "IPsec SA Established". The connection won't return until I do a manual disconnect/reconnect. 


On a possibly related note, it's listing Dead Peer Detection as disabled, even though I've enabled it on both the client and server side. Any thoughts on that?
