Firewall Rules

A firewall has two default rules, one for inbound traffic (WAN to LAN) and one for outbound traffic.

Inbound Rules (Port Forwarding): These rules restrict access from outsiders. The default rule is to block all access from outside except responses to requests from the LAN side. You can use Port Forwarding to add predefined or custom rules to specify exceptions to the default rule.

Outbound Rules (Port Blocking): These rules control access to outside resources from local users.The default rule is to allow all access from the LAN side to the outside. You can use Port Blocking to add predefined or custom rules to specify exceptions to the default rules.
