Raising Private Server max Ping?

I may have posted this in the wrong section first with out thinking… But my clan just got a server up and running its in oceanic I get like 220 ish ping not a big deal for me or them, but by default my ping is too high and server is rejecting me. And last time we had a clan server up we had guys from all over the world so we had to sort it out. But the admin who ran the server last time is not around now so I got no clue how to advise new guy to remove or raise the max server ping so US members can play with them with out having to rent a second server and divide the clan.

Any one know how you can do it?
