Quake 3 and PSO.
To connect to PSO, go to http://sylverant.net
and download/burn the patcher disc. Use this disc as a boot disc and it will force a copy of PSO to connect to the sylverant server.
For Q3A, enter all relevant settings in the connection screen (gateway etc), then in the primary ip, set it to 22.214.171.124 , that will connect the game to the DC Talk server list which always has at least 4 active servers.
