DMZ
If you have a client PC that cannot run an Internet application properly from behind
the NAT firewall, you can open the client up to unrestricted two-way internet access
by defining a virtual-DMZ (virtual-demilitarized-zone) host.
Figure 5-5 DMZ Settings
Enable
– Enables the feature. (Default: Disabled)
IP Address of Virtual DMZ Host
– Specifies the IP address of the virtual DMZ host.
(Range: 192.168.1.1 to 192.168.1.254; Default: 0.0.0.0)
Note:
Adding a host to the DMZ may expose your local network to a variety of security
risks, so only use this option as a last resort.
Firewall
The RG230 provides extensive firewall protection by restricting connection
parameters to limit the risk of intrusion and defending against a wide array of
common hacker attacks. You can also block access to the Internet from clients on
the local network based on IP addresses and TCP/UDP port numbers, or specific
MAC addresses.
Figure 5-6 Firewall Setting
Enable
– Enables the feature.
Disable
