Use ssh -X, not telnet. ssh will then tunnel your X connection for you.
Get your SGI sysadmin to install ssh on that machine. If you do this,
you can close telnet on your firewall (port 23) which you should have
done anyway, and you can keep the X ports closed. On my firewall at
home I have only port 22 open. Everything else is tunnelled through
that port, including X.
Opening the X server ports on your firewall is a Very Bad Idea (X itself
is an unencrypted protocol, and not very secure)
However, in answer to your question, the port is 6000+display_number,
so:
:0.0 is on port 6000
:1.0 is on port 6001
:2.0 is on port 6002
etc etc.
(remember X11 in general can support multiple independent servers,
although Apple's server can't do this)
