Sorry about the length of this post, but I have no idea what I'm talking
about, let alone explain it!

We have two sites (Head Office and Remote) with a Netgear FVS338 VPN
firewall at each end. The remote site connects via a Terminal Server and
runs a couple of EPOS systems.
Our setup in the Head Office is thus:

Workstation -> SBS 2003 R2 Standard -> FVS338 VPN Firewall -> Internet
Router

Recently, the VPN keeps dropping and if I set up a permanent ping I can
see that several times a day we get 7 or 8 pings timing out. This is
enough to kill the EPOS connections.

Making a very, very long story short, I've set up various permanent pings
and discovered this.....
If connect a workstation directly to the Internet Router there's no
problem.
If I connect a workstation directly to the FVS338 there's no problem.
If I connect the workstation to the network via the SBS box I get the
pings dropping.

I've changed the router and firewall with no success and Netgear tech and
the ISP are convinced the problem isn't with them (after several days of
diagnostics).

As luck would have it, I'm setting up a SBS 2008 box to replace the SBS
2003 and this is now sitting on a different ip address using a different
FVS338 connected to the same Internet Router. This is pinging away quite
happily without any drop outs.

I'm now beginning to suspect that problem is sitting on our SBS 2003 box
but I have absoloutly no idea where to look.
Has anyone come across this before and, if so, throw me a few pointers?

Many thanks.


If you swap the two Netgear FVS338 routers, does it still happily ping? If
not, I suspect an issue with the router.

For example, we had an issue with an ASA5505 that would not keep the
unlimited time-out setting I set on VPN tunnels. It wound up being a known
issue on the IOS, which I upgraded to the latest version and now works fine.
