Sorry, I am a bit unsure as to how to add these lines from either the GUI or CLI. It would be great to get step-by-step instructions.
NOTE: The last time I made GUI changes to the Firewall Policies, I unfortunately manage to lock up port eth2 of my 192.168.1.0/24 subnet and took down all my users. Don't want to do that again.
I've provided my current configuration for your review to make sure that the items you are recommending is still valid?
If valid, I am willing to try via either the CLI or GUI if you can give step-by-step instructions. GUI is probably more simple given step-by-step?
I've provided two screenshots of my current Firewall Policies and NAT settings via the GUI. Hope that helps.
Thank you.
