13-4 Firewall
LAN-to-LAN/HomeSafe means the LAN to the HomeSafe LAN interface. This is always
allowed, as this is how you manage the HomeSafe from your local computer.
13.3.2 WAN-to-LAN rules
WAN-to-LAN rules are Internet to your local network firewall rules. The default is to block all
traffic from the Internet to your local network.
How can you forward certain WAN to LAN traffic? You may allow traffic originating from the
WAN to be forwarded to the LAN by:
Configuring NAT port forwarding rules in the web configurator SUA Server screen or SMT
NAT menus.
Configuring One-to-One and Many-One-to-One NAT mapping rules in the web configurator
Address Mapping screen or SMT NAT menus.
Configuring WAN or LAN & WAN access for services in the Remote Management screens or
SMT menus. When you allow remote management from the WAN, you are actually configuring
WAN-to-WAN/HomeSafe firewall rules. WAN-to-WAN/HomeSafe firewall rules are Internet to
the HomeSafe WAN interface firewall rules. The default is to block all such traffic. When you
decide what WAN-to-LAN packets to log, you are in fact deciding what WAN-to-LAN and
WAN-to-WAN/HomeSafe packets to log.
Allow NetBIOS traffic from the WAN to the LAN using the WAN IP web screen or SMT menu
24.8 commands. Forwarded WAN-to-LAN packets are not considered alerts.
