Firewall UDP traffic,
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?

Yep, kvnsdr is spot-on. In Checkpoint for example you would define a "service" and specify UDP port 2300 for it. Then you put a rule in allowing this service to / from your networks.
Yes, that's all there is to it. Define a 'Service' and specify port range 2300 to 2300

as in open traffic from NETWORK A to B on say on port 2300
and open traffic from NETWORK B to A on port 2300???
