Nothing @Port80 ;) , the HOST PC (Firewall/Router) must have a opened Port to receive Clientmessages and then it work's i have UMTS i can't HOST games :( but conect to other Host's is possilble ever the HOST PC have open the Port and nothig other blocks the Message.
Which port a App use is NOT a LAW !! But the Portlist where exist, suggest you which Port you schould use, if Port's are a Law and each Port can use only one Times for a Task btw. for a APP what would you do when all Port's are reserved ?! ;)
In a case you have a App's like Xampp you can't host another Task which is use Port 80 for TCP (and UDP !?) , Xampp listen on it.
