Correct.

Thinking about it - yes, I'm sure that I did NOT use the same NIC on
both segments.  When it worked out of the box, I used the builtin NIC,
which was the only one available at this time.

When I've got to use -from, I'm using the docking stations NIC, which
is NIC #2.

Almost.  XWin.exe doesn't seem to "think" ;)  To me, it looks like
XWin.exe always uses the "IP" of the first NIC, even if it doesn't have
an IP.

Guess so.

Nope.  Docking stations NIC is #2, and XWin seems to take #1 - always.

Well, because of "great" design, I wouldn't be able to use any NIC at
all in that case.  So that's not an option.

Will have a look.  Thanks.

Uhmm - guess not ;)

Thx!

However, what about the colleague of mine?  He's unable to connect even
with -from.  As I said, he was connected to the same network segment and 
hub, when I wrote the first message.  He's using the same type of
notebook I'm using.  And finally, he's trying to connect to the same
HP-UX workstation I'm trying to connect to (to be on the safe side, we
did not try to connect to it at the same time.  I doubt that this can
cause problems - but we didn't want to try).  And it's possible to 
traceroute to and from his laptop.

Thanks again,
Alexander
