Firewall Rules Overview
Firewall rules (also referred to as service rules) are used to block or allow specific traffic
passing through from one side to the other. You can apply the firewall rules for blocking and
allowing traffic on the VPN firewall to LAN WAN traffic, DMZ WAN traffic, and LAN DMZ
traffic.
Inbound rules (WAN to LAN or DMZ) restrict access by outsiders to private resources,
selectively allowing only specific outside users to access specific resources. Outbound rules
(LAN or DMZ to WAN) determine what outside resources local users can have access to.
Default LAN WAN Rules
The VPN firewall has two default LAN WAN rules, one for inbound traffic and one for
outbound traffic:
• Inbound. Block all access from the Internet (the WAN) except responses to requests
from the LAN.
• Outbound. Allow all access from the LAN to the Internet.
For information about changing the default LAN WAN outbound rule, see
Default Outbound Policy for LAN WAN Traffic on page 222.
