If this is for Interlude check this changeset in L2J:

http://trac.l2jserver.com/changeset/5108

 

The problem is with MMOCore, have fun with a 5k+ lines patch :D

import com.l2jserver

Until it's a reworked pack, it's not IL.

 

But you're probably right about the fact you need to update MMOCore.

I just want a code for gracia final security for l2jattacker and ddos.any shares?

DDoS has nothing to do with L2J, from near or far, stop with that urban legend.

 

Try to read L2J timeline perhaps ? Search for IPV4Filter implementation for example...
