Example - you have a LAN consisting of 4 PC's, one of which is a machine connected to the
internet via a modem (analog, cable, or ISDN) connection and running GunnProxy.

Proxy Server
uses ISP assigned IP
address. If possible use a static IP address provided by your ISP (modem e.g. 203.26.169.1) and a LAN IP: 192.168.1.1
MASK: 255.255.255.0

Every machine on your network that you want to be able to access the internet from must
have a TCP/IP protocol stack installed. The TCP/IP protocol can be added in the network control panel.
To bring up the network under Windows 95/98 right click on Network Neighbourhood. Then double click
on TCP/IP for your network card. If it's not installed press Add then select Mircosoft on the right panel then
click on TCP/IP.
Once installed you must configure the IP Address of each machine.

The Proxy bridges all internal LAN connections between the ISP assigned IP address and the
internal LAN TCP/IP addresses. Therefore all browsers, email clients, and other internet applications
running on the LAN must use the proxy to send and retrieve information.

Start by configuring each PC connected to the proxy server. Install TCP/IP on each machine and
give each machine a unique TCP/IP address (e.g. start from 192.168.1.1 and work upwards). Specifiy
255.255.255.0 as the subnet mask.

Once this is complete you can configure your browsers, email programs, and other applications that access
the internet to point the proxy server.

***IMPORTANT NOTE FOR ALL USERS***
Make sure you set up your DNS to point to the GunnProxy server machine. If you do not this up SOCKS will not work. To do this, click on the DNS tab and enter anything as your host(client1, client2 .. etc) and add the IP address of the GunnProxy server as the DNS server. For example if your Gunnproxy server machine is 192.168.1.1, then the DNS of ALL your client machines would be 192.168.1.1

NOTE: It makes life alot easier if your ISP can provide you with a static IP if you're setting ports specifically on certain
ports on a particular IP address. Eg: You want people on the Internet to have access to a port but not the people on your
LAN. You would specify the IP address to listen on, eg 203.26.169.1 on port 80.

Common Questions

Question: "I've followed your instructions but I can't connect to the proxy server. What's wrong?"

Answer: You should check your cables. Try dropping back to MSDOS prompt while in Windows 95/98/NT and type
ping <proxy server machine> (eg: ping 192.168.1.1 ) If you see 'request timedout' then TCP/IP isn't installed properly. You should
check your settings.

Question: "My web browser does nothing, and I can ping the proxy server. What else could be wrong?"

Answer: If you are using SOCKS, check to make sure you have set up your DNS to point to the GunnProxy Server. For example: If your IP address is 192.168.1.2 and the GunnProxy server is 192.168.1.1, the 192.168.1.2's DNS would be 192.168.1.1
