How do i block incoming packet for IP 1.2.3.4? I wanna disable some building in newwork game. I thought if i could block specific packet i could disable some buildings or set limits.

Do you have a firewall?

[rain-13]

No, Does any firewall allow me block specific packed? Like if packet data contains 3c00000000ff54 then block packet?

I would also block outgoing packets. I want blok outgoing packets so that if i send chat message that starts with . then i want hide it from others.

There u cant do that by firewall or any other network analyzers like Wireshark...Or to hook your computer network tcp connection wont work also as the packets will be most probably encrypted...

Only thing that you can do is to first find send function adress by tracing from the Winsock.Send command you can do this with ollydebug with any version after you find snd_fnc adress add that into CheatEngine then open that adresses in memory after you can put a breakpoint there to see the going packets without encrypted forms...After you should write your packet sender program in C# or C++ when you write that program after its easy to filter anything you want etc..

Or After "without encrypted forms..." for example you want to remove some chatpackets then after you put breakpoint send some chat like hi then game will pause turn back to CE then see what breaks(what accessing to snd_fnc) and nop there and try to send again a chat.If you see that that works i mean you can't write anything into chat then you should nop there also in olly and save exe to make that changes for ever

Sorry for the Bad English hope u can understand...

You can use WPE Pro for block the PACKET

You select your game and you create a filter with the good KEY to block
