37.2. Rulesets for the Internet

Under "Network > Provider > Profiles : Firewall", a firewall ruleset is assigned to each provider. The firewall ruleset assigned to the active Internet provider decides which packets from the Internet may and may not be allowed onto the local networks.

Again, only the firewall ruleset assigned to the source of the packets (i.e. Internet and thus provider) decides whether the packets are allowed through or not.
