Hi, so I just installed the boxed edition of FSX so me and my friend can do shared cockpit (He doesn't have steam). We both have the gold edition + the acceleration pack installed. So I made my own LAN server, portfowarded it and all that good stuff, and he can join the session and get into the cockpit with me. But every time I (I'm the host) do something in the cockpit it takes a good three minutes for it to show up for him. Yet when he does something it shows up almost instantly for me. Does anybody know why this could be?

Thanks.

what airplane you using?

make sure his windows FW is off
