Firewall Options

The RG230’s firewall enables access control of client PCs, blocks common hacker

attacks, including IP Spoofing, Land Attack, Ping of Death, Smurf Attack, TCP null

scan, ICMP defect, and TCP SYN flooding. The firewall does not significantly affect

system performance and it is best to leave it enabled to protect your network.

Figure 5-13 Firewall Options

Enable Hacker Attack Protect – Network attacks that deny access to a network

device are called DoS attacks. DoS attacks are aimed at devices and networks with

a connection to the Internet. Their goal is not to steal information, but to disable a

device or network so users no longer have access to network resources. The Router

protects against the following DoS attacks: IP Spoofing, Land Attack, Ping of Death,

Smurf Attack, TCP null scan, ICMP defect, and TCP SYN flooding.

Discard PING from WAN side – Prevents pings on the unit’s WiMAX interface from

being routed to the network.

Discard to PING the Gateway – Prevents any response to a ping to the unit’s IP

address.

Drop Port Scan – Prevents outside hackers form testing the TCP/UDP port

numbers on the unit for any services.
