RealVNC questions about ports and display number

I still can't connect to pc2 from work. When I try out the vncviewer
with http://xxx.redriectme.net:1 or http://xxx.redirectme.net::5091 i
get error mesage "unable to connect to host: connectin timed out
(10060)".

Any idea what is wrong?

I still get on pc2 this:

81.191.xxx.yyy is accepting connections on Display 0 (TCP port 5900).
81.191.xxx.yyy is accepting connections on Display 1 (TCP port 5901).

For now to control pc2 i use vnc to pc1 and from there winxp
remotedesktop, not a ideal solution because of lagging etc...... Maybe
I'll try logmein.com for pc2 if I don't solve this issue.
