Nevertheless, if your router offers DMZ or “virtual

computer” features, you may be able to set it up by

 

 

yourself to enable KNS to work properly.

 

You will have to make the required adjustments, referring

 

to the instruction manuals for the devices you are currently

 

using, at your own risk. Generally speaking, you can use

 

any modem that is compatible with Microsoft®

 

NetMeeting®. If your operating system is XP, switch off the

If you must use a router with built-in modem, try setting

 

up a bridge. In this case, however, some ISPs will not

 

issue an IP address. To solve this, you can either set up

 

another router (compatible with Microsoft®

 

NetMeeting®) externally, or have an IP address issued

 

using a PPPoE* client.

 

(A PPPoE* client is available as a standard feature of

 

Windows® XP.)

 

Be aware that you do all of this at your own risk.
