B3 is necessary for a server ? i Mean if you dont do anithink from B3 can anyone see you in server list?

B3 is just a RCON Tool, you can host a server without it.

And pepole can see me if i dont use B3 ?

Yes, you will be able to see your server even if you don't have B3.

ok if that is corect then whats the problem with my server ? i dont see mine server on any lists ex:internet,lan

But i can conect on mine server and if i tell the ip friends can do the same !!

How you explain that?

 

Oh and btw thanks for helping me i hope figurit out and at the end see my server on server lists

It could be that your router is unable to query your IP, so you wont be able to see your server in the server list.

Can your friend see your server in the "Server List"?

No he cant but both (me/him) can connect by (~) command
