Firewall UDP traffic,
Posted on 2007-10-09
Correct me If I am wrong here, I guess when you setting up a firewall in particular TCP connection its very much depending on who initiate the connection. So for instance if
Network A wants to communicate to Network B
In this case, we can just setup TCP allow Network A to Network B. This is because TCP is a stateful packet.
How about for UDP?
If Network A wants to communicate to Network B?
Do we need to allow packet from
Network A to Network B and
Network B to Network A?
