Please help...

I have problem having a LAN game with my brother..
I do everything ok i become the host and he is the client and the game starts quite nice..but there is one great problem...when i shoot him down
in my computer he is going down on flames but in his computer he is flying like this never happened and he can also shoot me down...and the same thing happens to me...he shoots me i am on fire on his pc but i am flying like nothing happened...

What i am doing wrong... can anyone help...its making me crazy bexause even if we fly together we cannot shoot each other.. THANKS

You guys are on the same network- using the same connection?

Don't use the LAN button- it never worked. Use the Internet button and connect as though you are in 2 different locations.

Also- your router may not be set up correctly, but it is very odd that you can fly in the same room, but this happens. Typically you can either connect- or not.
