Yes, that is right for Jedi Outcast. For Jedi Academy it is 2907x where x is 1-5. If they do the command you listed they have to do /net_restart to make it take effect. It's easier to make a shortcut to jk2mp.exe or jamp.exe then edit the Target line to add +set net_port 28071 (for jk2) or +set net_port 29071 (for JA).
