Basic Firewall Background

As a device on the Internet, a Cayman Gateway requires an IP address in order to send or receive traffic.

The IP traffic sent or received have an associated application port which is dependent on the nature of the connection request. In the IP protocol standard the following session types are common applications:

ICMP

HTTP

FTP

SNMP

telnet

DHCP

By receiving a response to a scan from a port or series of ports (which is the expected behavior according to the IP standard), hackers can identify an existing device and gain a potential opening for access to an internet-con- nected device.

To protect LAN users and their network from these types of attacks, Break- Water offers three levels of increasing protection.

The following tables indicate the state of ports associated with ses- sion 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.
