Is 0. I didn't explicitely disable, it only happens to be so.

Now this is interesting:

I try a simple telnet www.thedeadman.com 80 (I will post the publicly available
servers name if you want me to) and this is what happens:

not working: (connection fails)
2.0.39, some 2.2.18, 2.4.10, 2.4.13, some 2.2.19

working:
some 2.2.18, some 2.2.19, 2.4.5, 2.4.15-pre3, 2.4.15-pre7

?

Stephan
