11.4.1 LAN to WAN Rules
The default rule for LAN to WAN traffic is that all users on the LAN are allowed non-
restricted access to the WAN. When you configure a LAN to WAN rule, you in essence want
to limit some or all users from accessing certain services on the WAN. WAN to LAN Rules
The default rule for WAN to LAN traffic blocks all incoming connections (WAN to LAN). If
you wish to allow certain WAN users to have access to your LAN, you will need to create
custom rules to allow it.
