How is my firewall rule?

I am using a westell 327w modem/router combo with built-in hardware firewall.

I am using its medium setting rule which is same rule as high setting but end user can edit the Nat configuration.

I'd like to know how good the factory default rule is. cuz I have seen some harder syntax around and I am wondering if I need to edit the default rule.

Its 327w's default rule, I would post it here if I know how to. those lines wrap up into a mess whenever I try to copy/paste.

thank you for reading.
