VPN through Linkys WRT54GC

I establish a VPN through a Linksys WRTGC v2.0.
This VPN is dropped after 15 minutes and 30 seconds, but do not ask me why?

When I replace in the same configurration the Linksys by a Belkin Wireless
adapter, the VPN stays up until (after more than 1 hour) I disconnect. And
that is the way we want it.

Why the connection is dropped when linksys is in between the both PC's we
would like to know?
We discussed this with the linksys help department, and they decided to
replace the WRT54GC by another one, but that is so far no solution. In other
words, new machine with the same old problem.

Has anyone any idea that can solve this problem?

Switch to Belkin.

if you are running thru an address translation then your VPN client is
probably doing encapsulation to protect the IPsec security. Try using TCP
instead of UDP.

i dont know the platform, but there may be a UDP session lifetime setting in
the Linksys - increasing that should improve the timeout, or adding a
keepalive on the client would avoid the timeout.

mind you if you have a critical application it is usually better to test it
before you commit to buying a bunch of kit.....

Another possibility is DHCP lease renewal problem. Try increasing the
DHCP lease time.

We did test before with several routers. The WRT54G v4.0 works fine.
We are unable to make a VPN through the WRT54G v5.0
With the WRT54GC we have the time-out problem.
The VPN is a simple pptp-connection. We can (as far as we know) only
configure the the DHCP leasetime (standard 1 day, up to 4320 minutes)
