hi daren,

the short answer is no.  this is a topic that has been discussed several
times in the past.  i would recommend that you go to the list archives (the
url is in the footer of every list message) and search using one of the
following: "pcanywhere", "portfwd", "port fowarding", or something similar.  

basically, sun/cobalt did not include a way for you to forward ports using
the qube3's web gui (see:
http://cobalt-knowledge.sun.com/cgi-bin/kbase.cfg/php/enduser/std_alp.php
and use ref id# 010518-017562).  however, there are several ways you can
still do this.  for example, you could configure and use ipfwadm (or is it
ipchains?).  ipfwadm (and/or ipchains) is the most direct way for you to do
it, but they entail a learning curve and quite a bit of linux savy, which
i'm afraid i can't help you with.

other possibilities, which you can read more about in the archives, are to
install a third party program such as portfwd (go to source forge -
http://sourceforge.net/ - and search on "port fowarding" for more
examples).  we use portfwd, and have done so on both a qube2 and our current
qube3.  this utility works great, although there can be installation issues.

we just had a thread at the beginning of this month about using portfwd and
pcanywhere.  in that thread, rw black was able to get everything working
finally, but it did take quite a bit of fooling around.  again, look in the
archives and see what has been said in the past.

on this, do be careful because of course it is possible to break something,
or more likely void your warranty.  i don't believe that you can use the web
gui to do the forwarding.  if you do want to try and configure the system as
it is now (i.e., using ipchains/ipfwadm and not installing any other
programs), then i would certainly search the web for tutorials and how to
pages before attempting anything yourself.

anyway, after reading the archives and researching your options a bit more,
please do post any additional questions that come up.  and in any case,
report back here what you finally do try and the experiences, problems, and
successes you have.

good luck,

mikey.
