What do you mean Original online server? For SWBF1, I have swb1 game, but as far as I know, I don't think there are any servers still up.
Well the Arena is kinda a permanent server(PC-Dedicated). It cost money to run it from a server company. However if you are looking for a free PC-Dedicated server, I can tell you where to get one. It will be a lot more laggy than the arena, but has the same program.
