16.3 Connection Direction
This section talks about configuring firewall rules for connections going from LAN to WAN and WAN to
LAN in your firewall.
16.3.1 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 Policy -> LAN to WAN -> Rules, you in essence want to limit some or all users
from accessing certain services on the WAN. See the following figure.

16.3.2 WAN to LAN Rules
By default NO incoming connections (WAN to LAN) are allowed unless you create rules allowing certain
WAN users access to your LAN. See the following figure.
