Frequently Asked Questions
IP Telephony System
Will the System function in a Macintosh environment?
Yes, but the System’s setup pages are accessible only through Internet Explorer 5.0 or Netscape Navigator 5.0 or
higher for Macintosh.
I am not able to get the web configuration screen for the System. What can I do?
You may have to remove the proxy settings on your Internet browser, e.g., Netscape Navigator or Internet
Explorer. Or remove the dial-up settings on your browser. Check with your browser documentation, and make
sure that your browser is set to connect directly and that any dial-up is disabled. Make sure that your browser is
set to connect directly and that any dial-up is disabled. For Internet Explorer, click Tools, Internet Options, and
then the Connection tab. Make sure that Internet Explorer is set to Never dial a connection. For Netscape
Navigator, click Edit, Preferences, Advanced, and Proxy. Make sure that Netscape Navigator is set to Direct
connection to the Internet.
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. It is recommended that you set your computer with a static IP if you
want to use DMZ Hosting. To get the LAN IP address, see “Appendix E: Finding the MAC Address and IP Address
for Your Ethernet Adapter.”
If DMZ is used, does the exposed user share the public IP with the System?
No.
Does the System pass PPTP packets or actively route PPTP sessions?
The System allows PPTP packets to pass through.
Is the System cross-platform compatible?
Any platform that supports Ethernet and TCP/IP is compatible with the System.
Which modems are compatible with the System?
The System is compatible with virtually any cable or DSL modem that supports Ethernet.
How can I check whether I have static or DHCP IP addresses?
Ask your ISP to find out.
How do I get mIRC to work with the System?
Under the Router => Applications tab, set the Starting and Ending Ports to 113 for the computer on which you are
using mIRC.
