I have SFOS 17.5.5 MR-5 running live for my home network. I am trying to set up port forwarding but have been unsuccessful so far but that is a different story. I might have inadvertently made changes to default firewall rules. Can someone confirm if below are default values from a fresh installation?
Could be, if you run the wizard and selected different configuration steps.
You should install MR6, to get rid of those broken Icons. Than you can see, which rule is currently enabled.
This KBA explains the current way to use DNAT. (NAT).
If I delete all rules that are disabled (like top 3 rules in the picture), will it break my firewall? I don't think so since they are not enabled but would like to know for sure.
In reply to Jason Lim:
no you will not break your firewall by deleting those rules.
