C# udpclient/udp socket -- working locally but not on global addresses -

i have annoying problem. have mirc/skype application, meaning chatroom text , voice. text & chatroom stuff goes through tcp , works flawlessly, while udp relays recorded data other connected clients.

between 2 clients on home network, audio transfer works fine. against global client, server niether receive packets him, or receive packets server.

here's example:

server using udp socket while client using udpclient, result same anyway , works locally too..

server global ip: 222.222.222.222 server local ip: 192.168.2.3 server port: 9999

client global ip: 111.111.111.111 client local ip: 192.168.0.100 client port: 8888

the server *binds socket 192.168.2.3 : 9999 *receives 111.111.111.111 : 8888 *sends 111.111.111.111.111 : 8888

the client *binds socket 192.168.0.100 *receives 222.222.222.222 : 9999 *sends 222.222.222.222 : 9999

...you mean. have no idea why data dosn't through. i've tried sending/receiving on port 53 (for both client , server) , shouldn't necessary right? mean traffic should go through anyway (just games call of duty) , no there no windows firewall active, router in case.

the client/server uses connect() each other, not receivefrom/sendto. tried using no difference.

i no exceptions or either impossible debug :(

what possibly reason? consider fact works locally not globally; agree sounds firewall issue, i'e described above dont see how thats applicable in scenario, , tried on port 53 , other open ports..

cheers :)

edit: quite alot of code, if necessary can copy in

you can't broadcast udp entire internet (i assume mean 'global') - work within subnet of machine issuing broadcast. why works locally not remote machines.

you might want consider using ip multicast instead:

that said may have problems routers (that have no control over) not allow multicast packets forwarded.
