Creating Custom Rules

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.
Figure 16-1 LAN to WAN Traffic
16.3.2 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.
