as far as i know all you need to do is have the qube forward incoming
traffic on whatever port or ports pcanywhere uses (ask them what ports to
forward, or look it up at:
http://www.redhat.com/support/docs/tips/urls/txt/port_numbers). 
unfortunately, the qube3 does not ship with port forwarding built in, so you
will have to either research ipchains and learn how to do it yourself, or
install a third party utility to do it for you.

we use a port forwarding daemon called portfwd on our qube3, and i have
posted several articles about how to install this utility.  take a look at
the following article from the archive for a recent discussion:
http://list.cobalt.com/pipermail/cobalt-users/2001-August/051078.html

here's another article discussing pcanywhere, and portfwd on a qube2 (note
that the qube2 is mips based and a qube3 is i386 based, so the details of
installing portfwd are slightly different, the previously mentioned article
discusses this a bit):
http://list.cobalt.com/pipermail/cobalt-users/2001-February/034861.html

you can also go to the archive (see the list footer for the address) and
search using "portfwd" or "port forwarding" (and for that matter
"pcanywhere") for more articles.

good luck,

mikey.
