There's no such option.

It can't be done. The MAC address is hidden by the IP protocol, and it's pretty much impossible to rely on really.

In theory, you can get the MAC address, because that is what all routing is done by.

If Unreal can get the MAC from the OS is a different question. Chances are, if there were a way to get the MAC from the OS would take more resources and slow the server more than it is nesassary to just to display one more bit of useless information to the clients. Getting a MAC, however, can be a useful thing if you were intending to actually use it for something (like static server bans).

I do not think there is a way for Unreal the get the MAC address from the OS.

i wanna use it for banning , of course... the MAC-ADDRESS is already exists it the packet recieved by the server (with dest port , src port , ip and the rest) , but i don't know where's the code for the actual full packet (after decode) .
btw , maybe i'm confused about the concept (MAC-ADDRESS) , maybe it's another data , but anyway i need to know where do i have the full decoded packet data (with headers) on the server functions

It's not possible.
The server can't know the mac address of the client. That's how the internet works.

It could only get the mac address if it were in the same LAN - but there such a feature is pretty useless, because you most probably know all the clients...

Oh and:
You are aware: The mac address can be changed too...

Right, it's only possible on a network without any l3 routing (read: routers), so typically a LAN with some hubs/switches etc.

You are aware: The mac address can be changed too...

Exactly, and it's easy too...
This site has a nice overview of how to do it by OS.

Maybe it's called MAC-ID?
btw , i am aware of possible changes to this address , but not everybody knows how to change it ...
anyway , can you tell me please on which file & function i've got the full decoded packet (with headers) or there's no such option (i'm compiling it for windows XP)?

Modifying the source is not supported.

Lets also not forget that MAC addresses are for LANs only. If you're using dialup, you don't have a MAC address.

Anyway, the question has been answered, so there is no reason to keep asking about it *locked*
