Uh, the timeout I was talking about is in the firewall or NAT, not libcurl.

It really doesn't matter what your application is. If the reason for the
problem is the timeout I'm guessing at, then there's not a lot your app or
libcurl can do. You'd need to make some kind of work around in your app to
make sure the transfers are always shorter than the timeout period.

You can of course easily test if this is what's happening and then you'd know
for sure. If it isn't this timeout, then I'm very puzzled to what it would be
and we'd need to start digging for real to find the cure.
