I am troubleshooting a PPTP VPN between two sites. Both are W2K Servers,
fully patched, with RRAS running on each of them. The firewall is a Belkin
unit and has the appropriate ports open/forwarded.

We are experiencing the symtoms of a timeout, where the VPN connection
appears to stall after a few hours. The connection remains up, and we can
transmit however we cannot receive. The symptoms occur on both persistent
connections and dialup.

I've checked all timeout paged and insured that they have remained off.

What am I mising?

I would like to know the details of this issue. Can you please check the
following ?
a) Do you have the group policies governing a set of users with session
timout equal to 1 min? such as quarantine policies?
b) Do you see any interesting info event viewer logs?
c) Is it okay for you to post the tracing logs. You can do this using
following commands

1) netsh ras set tracing * dis
This will disable all RAS related tracing, if any,

2) Go to %systemroot%\tracing directory and delete all old tracing files.
You may want to take a backup first.

3) netsh ras set tracing * en
This will enable all RAS related tracing.

4) Try to recreate the issue and disable the tracing afterwards (using step
1).

You would need to do this on both sides simultabeously. If you can post both
the server side and the client side logs, we can investigate it.
