I refered to the letter Ragnarok - block port 5000, 6900.

To Loceng Cat - you and all Internet Service Providers (ISPs) will never ever be able to block any port. I and many other gamers have many ways of bypassing these so-called security procedures to block your kids from playing computer games.

Just a simple forum update will ensure that all gamers will still be able to access the servers. And even if you manage to close down the Ragnarok game server in Malaysia, there are still plenty of Ragnarok servers around the world or even privately-owned Ragnarok servers ... try banning that!
