To protect LAN users and their network from these types of attacks, BreakWater offers three levels of
increasing protection.
The following tables indicate the state of ports associated with session types, both on the WAN side
and the LAN side of the Gateway.
This table shows how inbound traffic is treated. Inbound means the traffic is coming from the WAN into the
WAN side of the Gateway.
This table shows how outbound traffic is treated. Outbound means the traffic is coming from the LAN-side
computers into the LAN side of the Gateway.
