Are you talking EQ or in general?

First off you kinda need to know what packet exactly you are looking for. If you do not have a packet sniffer, and even then most scramble packets using CObfuscator. Once you know what the packet is...i.e. :

#define SP_SpeedCrash                   0x7EE  // 18 Jan 2008

You can then block it:

PLUGIN_API BOOL OnSendPacket(DWORD Type, PVOID Packet, DWORD Size) 
{ 
if (Type == SP_SpeedCrash) return false; 
// speed hack protection 

Blah 
Blah
Blah
more code....
}

However, the problem you need to deal with next is the CObfuscator that scrambled the packets, and such. So not so easy unless you know your shit.

Client packets are different than server packets.
