Sorry for my bad English. I'll try to be explicit.

I have installed iFolder 3.1 (OES Linux SP1) on a server and iFolder 3
windows client (3.1.5230.1) on my laptop.

The WebAccess "srv1.mydomaine.com" works without any problem.

If I try to connect the client from a remote access, it can't find the
server and a tcpdump on the server see nothing.

Then, if I try to connect from the local network with
"srv1.mydomaine.com", I have the same result.

Then, if I try to connect from the local network with the IP
192.168.0.100, it works straightaway.

Then, if I try again to connect from the local network or from a remote
access with "srv1.mydomaine.com", it works... for a few hours. Next it
doesn't work again.

Any idea ?
