Using Inbound/Outbound Rules to Block or Allow Services

Firewall rules are used to block or allow specific traffic passing through from one side of the
firewall to the other. Inbound rules (WAN to LAN) restrict access by outsiders to private resources,
selectively allowing only specific outside users to access specific resources. Outbound rules (LAN
to WAN) determine what outside resources local users can have access to.
A firewall has two default rules, one for inbound traffic and one for outbound. The default rules of
the FVS328 are:
• Inbound: Block all access from outside except responses to requests from the LAN side.
• Outbound: Allow all access from the LAN side to the outside.
These default rules are shown in the Rules table of the Rules menu in
