Frequently Asked Questions
Broadband Firewall Router with 4-Port Switch/VPN Endpoint
What is DMZ Hosting?
Demilitarized Zone (DMZ) allows one IP address (computer) to be exposed to the Internet. Some applications
require multiple TCP/IP ports to be open. You should set your computer with a static IP if you want to use DMZ
Hosting. To get the network adapter’s IP address, see “Appendix C: Finding the MAC Address and IP Address for
Your Ethernet Adapter.”
If DMZ Hosting is used, does the exposed user share the public IP with the Router?
No.
Does the Router pass PPTP packets or actively route PPTP sessions?
The Router allows PPTP packets to pass through.
Is the Router cross-platform compatible?
Any platform that supports Ethernet and TCP/IP is compatible with the Router.
How many ports can be simultaneously forwarded?
Theoretically, the Router can establish 520 sessions at the same time, but you can only forward 10 ranges of
ports.
Does the Router replace a modem? Is there a cable or DSL modem in the Router?
No, this version of the Router must work in conjunction with a cable or DSL modem.
Which modems are compatible with the Router?
The Router is compatible with virtually any cable or DSL modem that supports Ethernet.
How can I check whether I have static or DHCP IP Addresses?
Consult your ISP to obtain this information.
How do I get mIRC to work with the Router?
Under the Port Range Forwarding tab, set port forwarding to 113 for the PC on which you are using mIRC.
