The help file shipped with your Router normally covers detailed instructions how to setup Port Forwarding / Virtual Server.

• For D-Link Router (and comparable) click here or here (Topic "Virtual Server"). If you are not able to setup the router by yourself, please call the tech support number provided in your user's manual and ask a representative to help you forward ports (default port for the Http Server is "80", for the Streaming Server "8000").

• For LINKSYS Router (and comparable) click here or here (Topic "Forwarding" or "Port Forwarding"). If you are not able to setup the router by yourself, please call the tech support number provided in your user's manual and ask a representative to help you forward ports (default port for the Http Server is "80", for Streaming Server "8000").
  

Good Port Forwarding instructions for most every Router can also be found at http://www.portforward.com/.

For Linux/Unix Router read below:

If you are behind a router but want to access to the internal VisionGS Http Server or Streaming Server, please read the following.

1.) Requirements

• Linux Kernel with IP Masquerading support
• ipmasqadm

If you don't fulfill the requirements from above, skip to section 3. (Notes) of this article.

2.) Commands

To load:

where:

• 123.123.123.123 is your online (WAN) IP address (check ipconfig for it)
• 80 the external port (on the router); Default port for the Http Server is "80", for Streaming Server "8000".
• 192.168.1.106 the IP address (LAN) of the computer where VisionGS runs on
• 80 the port where the VisionGS Http Server (or the Streaming Server) runs on. Default port for the Http Server is "80", for Streaming Server "8000".

If you are using ports other than 80 please DON'T forget to edit the applet code matching to it (<PARAM name="port" value="80">).

To unload:

This will unload all portforwarding rules.

3.) Notes

If "ipmasqadm" is located in a directory other than "/usr/sbin/", DON'T forget to edit the command directory of "ipmasqadm" machting to it, otherwise you will get an error like "File or Command not found".

If you don't fulfill the requirements above or have trouble setting up IP Masquerading / ipmasqadm, you can use a freeware tool called PortFwd which forwards incoming TCP connections and UDP packets, located at http://freshmeat.net/projects/portfwd/.

IP Masqerading and PortFwd have successfully been tested with the HTTP- and Streaming Server of VisionGS.

4.) Support

If you have problems with Linux, IP Masquerading or Portforwarding in general, please DON'T contact us for support. Please ask in newsgroups, on IRC or your Linux vendor. All of this is third party and not part of VisionGS!
