Default firewall rules

Question

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.

Hi, 
 no you will not break your firewall by deleting those rules.
