Changing the function of the place package will not move forward, from the to send package manually. First find out what the package does, and what you intend to do with it.

Trying to protect it via iptables but still fail, this has something to do with world (channels).
I am looking for any possible idea that I can gather to fix my problem.

Look at the source of EP2 the function that deals with this package, probably if in EP8 without some problem in the source of EP2 will also have. Then just understand and look for the function in .bin and modify.

Fixed your WorldSvr.bin and it will solve your problem against channel crash.

That's my point, Yes i am trying to fixed the worldsvr bin but the problem is tbh, I dont have much idea how to figure it out or fix that string that cause crashing the channels, Also i found the hex string with something related on what x30 said, "F4"

on-topic: try changing the bad packet OP code to something else on SERVER-SIDE (0xA4 if i remember correctly)

edit: actual opcode is 0x0A not 0xA4 confusion was caused by the correct opcode 0xF4
