No error at all, just that the browser gets waiting to connect, and
nevers does it.  Pinging is always fine with no specification of
packet size.

I might try that.  What I'll do for now is enable new connections on
both sides, since the ones coming from outside are not accepted (but
that's the way that sounds common sense to me, and that has been
working on my debian box for quiet a while)...

Again, no error, just the browser not getting anywhere for some sites.
 Some others work as google and gmail...
