Thank you. I assume the router does NAT/SNAT/MASQUERADE (is your laptop IP something like 192.168.1.?) and you have a portforward on the router. Or is your IP public? The connection tracking tables can be bad if they are automatically "cleaned up". Can you give me the same details for the server side? I will also assume that you are using asymmetrical links, so the upload bandwidth is closer to 1Mbit/s - this is not that important yet though. In addition to this, could you run a 'tracepath your-server-name-or-ip' and tell me how many hops it counts. >> Also, some people have had success with Heartbeat Interval for FD and SD >> in similar situations (this specific error is pretty unique according to >> google, though). > > I haven't set that up.

This sounds awfully familiar. Tell me how it goes. You might be in luck if it was temporary. Otherwise, I get more material to solve it. /johan -- Johan Ehnberg Email: [EMAIL PROTECTED] GSM: +358503209688 WWW: http://www.ehnberg.net/johan/ ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
