I have a Netgear Prosafe Fvs318n Firewall - It connects via ssl Vpn tunnel.  My issue is after about 10 mins or so I'm getting disconnected from the firewall even though I'm working remotely.  I'm not sure what's going on.  It happens regardless if I'm wireless or on a lan connection and I've disabled my virus protection to rule that out too.  Anyone have any ideas?

few thing to consider:

do you get disconnected after the same period of time? - suspect a timeout setting

Are you disconnected after a period of inactivity (network inactivity like saving/opening files.... not inactivity on the PC) - suspect an idle timeout

set a ping running to a general internet address (like www. Hotmail .com) and see if your pings drop around the time you lose connection - suspect internet connection

Check if this occurs for other users or not - suspect either faulty PC or settings for a specific VPN user.

This is occurring on all users. I have a timeout for inactivity only and that's 60 mins.  The users are in the middle of working when it just disconnects.  I will try the pinging test to see if the internet is dropping.  the only answer I have for the disconnection issue is if I'm using Log me in .com it doesn't do that.

Could you please be more specific with 'working'...
are they actually accessing files/network systems via the VPN or do you mean 'working' as in editing a word document etc?

Yes they are remoting to their PC's (Desktops) via RDP and using program. I have the time out for 60 minutes unless I need to designate that some other way ie 3600 instead of 60 but I'm not sure.

If it is a timeout of 60 seconds instead of minutes, an enduring ping (-t) against the RDP target should help (for diagnostics).

Ok the time out is in minutes because it will only take up to 3 characters.

Were you able to test the effect of ping -t yet?

NO I'll have to try that now...  I'll let you know.  If it's disconnecting from the VPN then ping -t isn't going to tell me much?

pinging is fine between 70-84 ms

The interesting part is if the connection still gets closed, though the ping -t runs. The purpose is to reliably generate continuous traffic.
