How to access Joyfax Server behind a
For users on an office network with a router installed, Joyfax
Server is not accessible from the Internet because of many modern
routers' built-in firewall.
Enabling outside Joyfax Client access to an internal Joyfax
Server on an Office network requires that you set up NAT - "network
address translation," or port forwarding. Please follow this
- Step 1. Determine your server's
internal IP address.
All the computers on your internal network have an IP address which
looks something like 192.168.0.XXX. Get on the computer with the
server running open a command window. Then type ipconfig to
determine the machine's internal address, like so:
Windows IP Configuration
Ethernet adapter Local Area Connection:
Connection-specific DNS Suffix . :
. . . . . . . . . . . . : 192.168.0.98
Mask . . . . . . . . . . . : 255.255.255.0
Gateway . . . . . . . . . : 192.168.0.1
In this case, as you can see, the server's internal IP address is
- Step 2. Configure your router.
Most routers have an web-based administrative interface that's
located at http://192.168.0.1. (This address does depend on your
model. Consult your router user guide for more info.)
Once you've gone to the router administration, entered the password
(if one is set up), there should be an area called "Port
forwarding". There, you'll set the port number that
requests from the Internet will come in, and the internal computer
that should fulfill those requests. Here's a screenshot of the
Netgear router set up to port forward 8750 to the
Joyfax Server, which is at 192.168.0.98 (see above). Click on the

- Step 3. Determine your server's
internet IP address.
In the "Router Status" area, you may see your
Internet IP address in the Internet Port section.
So, in the Joyfax Client login dialog box, type 184.108.40.206 as
server address, then you may access the Joyfax Server all over the world
