creating a server and joined by a friend

[carapippino]

hi i have some problems configuring and let a friend of mine join the server

i use mame plus plus 0.119 with the kaillera included. i configurws the server in options-> kaillera server options, changing only the server ip with the one suggested by the check ip button

then i go to file -> start kaillera server

then i join the room from file-> kaillera netplay-> enter IP -> my ip (the same suggested by the check ip button), i enter successfully ( my ping is 0 ms, as it should be i think) but my friend can't reach it. we tried also viceversa (friend =server and me client, with no success)

i tried also to download the kaillera server 0.86, but we can't still get to connect each other

all this because we have great problems of desync almost everytime we play online (though in a room with low ping). i have 2 mbit internet connection, my friend have 1 mbit)

thx i nadvance
