Remote Desktop through NetBSD, losing connection frequently


I'm not a Unix/Linux pro, but I'll supply as much information as I can.

At home I have a NetBSD 2.0 box acting as my router/firewall/ftp, web & email server. It's worked so well for so long I've forgotten most of what I learned getting it going.

I now have a Win XP laptop with which I connect to my office through VPN. Once connected I use remote desktop to run apps on the office (Win) server.

Remote desktop never has a problem connecting, but I lose the connection about every two minutes. It reconnects after ten or twenty seconds, and I'm good for another two or three minutes. This problem only occurs when connecting from my home - when at client sites the connection is solid.

Can anyone suggest where/what to look for to track down the problem? I'll be happy to supply any log or setup info that would help.

Thank's in advance

Just some general suggestions; hope they can be of help.

The first thing I would look at is the VPN connection. Is it stable? If it has a log file you can check for errors there.
If the VPN seems to be fine you can try monitoring the network from your BSD box with
tcpdump |grep "XX.XX.XX.XX" > /home/myuser/mylogfile.log
where XX.XX.XX.XX is your office IP address. It will output a lot of info, so you may want to filter the output further, depending on the output you get.

One possible cause I can think of is that your vpn refreshes its connection every few minutes, and while doing so breaking your rdesktop connection.

Thank's stzein.

I did the tcpdump and let it ride through a disconnect. I've got about a Mb of stuff to sift through now.

I'll likely be back with follow-up questions soon.

Thank's again.
