I’ve a firewall rule that permits a client to go to the internet. I’ve simply dropped all traffic from client to zone RED (that is the internet) and vice versa.
Now I want to allow one specific port from the client to be accessible from the internet. I can set Port Forward up to allow that specific port from the RED zone to the client and vice versa, but isn’t my firewall rule gonna overwrite the port forward?
If it does, then what do you recommend, how should I allow only one port to communicate to the internet and drop every other communication from/to the internet?
