LAN-to-LAN/OX253P means the LAN to the OX253P LAN interface. This is always
allowed, as this is how you manage the OX253P from your local computer.
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.
•
Configuring
WAN
or
LAN & WAN
access for services in the
Remote MGMT
screens or SMT menus. When you allow remote management from the WAN,
you are actually configuring WAN-to-WAN/OX253P firewall rules. WAN-to-WAN/
OX253P firewall rules are Internet to the OX253P 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/
OX253P packets to log.
Forwarded
WAN-to-LAN
packets are not considered alerts.
11.2.2 Triangle Route
When the firewall is on, your OX253P acts as a secure gateway between your LAN
and the Internet. In an ideal network topology, all incoming and outgoing network
traffic passes through the OX253P to protect your LAN against attacks.
