Re: Subchannel
Ok. think of the cluster like this:
Login Server ---- Character Server --- Channel
Better explained like this ..... Authentication ---- Kern ----- 1-1
You can have multiple char servers and world servers like the official servers do.
However, I don't know if your pc can handle more than one world server or char server without severly lagging it.
To answer your question.
Keep the ISC the same, and use a different IP address for your char/world server(s).
And Caali server is not supported anymore. I gave you this because this pertains to all server construction.
