Hello everyone, this is my first message. I would like to ask your opinion on UDP communications. I have implemented a small (with lazarus) program that generates UDP hole punching. It works fine on the local network, but not as well on different networks over the internet. I have already asked for help on the lazarus forum at this address and we have come to some strange conclusions. For example we have doubts about using port forwarding with udp ports. The discussion can be found at this address:
