Hi, 

I have noticed something awkward. I can't connect to FreeBSD machines
on the net. I have no problems reaching other hosts (via ppp), but all
connections to FreeBSD machines seem to succeed, only to hang after 
the initial contact.

telnet freebsd.first.gmd.de
Trying 192.35.153.200...
Connected to freebsd.first.gmd.de.
Escape character is '^]'.

and then it hangs until the other side times out the connection.

http://www.freebsd.org
Contacting host ....
Host contacted, waiting for reply ...

and then it hangs until .....

the same for ftp/telnet to rah.star-gate.com which I suspect is also a 
FreeBSD machine.

It does succeed to wcarchive.cdrom.com and does not succeed to 
thud.freebsd.org

Is there some known interaction between FreeBSD 2.0.5 (my machine) and
other FreeBSD hosts? Presumably more current FreeBSD hosts?
freebsd.first.gmd.de is 2.2-current, and I don't know about 
www.freebsd.org.

Here's some info:

Does anyone have any hints for a solution to this anoying problem.
