NOTE If you are using a one-way cable modem, you will need to have WinProxy dial the ISP for the initial connection to the Internet. The return request will come in through a network card that is installed in the server; one for the connection from the cable modem and another card that connects to your hub and is used for your internal network connection. Some ISP's that have this type of setup require that you use their dial-up program to get connected. In this case, you can not create a dial-up networking connection that WinProxy can use to dial out. You will, therefore, need to manually dial using the ISP's program, and enforce the hang-up yourself. WinProxy will not be able to hang up the connection for you. Your client computers on the network will be able to connect to the Internet.

Below is the information you will need to obtain from your Internet Service Provider (ISP). Having this information beforehand will make WinProxy's initial setup a quick and easy process. This information will be needed if you are setting up access through a standard ISP. It will also be needed if you'll be using AOL as your provider. Mail and news server addresses are not needed for 3.0, but it's a good idea to have them anyway.

The IP address(es) of your ISP's DNS servers. These are often given as the primary and secondary DNS servers. You will use the IP address of the primary DNS in the Properties Wizard. As a last resort, if you know the domain name but not the IP addresses of your ISP's DNS servers (and can not obtain them), WinProxy can find the IP addresses. In WinProxy, click on File => Settings => Protocols => DNS Setup => Find_My_Name_Server!!

This can be either the numeric IP address or the name of your ISP's news server. If using the name of the news server it will be in a form similar to news.myisp.com. The last extension differs with the type of organizations which owns the server you use (commercial, governmental, educational, etc.). Thus the example you see here with the extension "com" could just as easily be substituted with "net", "gov", or "edu".

Address This can be either the numeric IP address or the name of your ISP's SMTP server. This is the address of the server to which you send mail. It will look something like this: smtp.myisp.com.

Address This can be either the numeric IP address or the name of your ISP's POP server. This is the address of the server from which you have been getting your mail. It will look something like this: mail.myisp.com. NOTE:- At many ISPs the SMTP and POP servers are at the same address; at some they are not.

Your ISP will assign you either:-

1. a static IP address, which means your IP address to your external connection will remain the same with every new connection you make to the Internet, or
2. a dynamic IP address, which means that your IP to your external connection will change every time you make a connection to the Internet.

WinProxy works with either type of IP addresses from your ISP, i.e. it will work regardless of whether your ISP is assigning your dial-up adapter a static IP address or a dynamic IP address. The reason being that WinProxy is configured to use the internal network card that connects to the rest of your local network. This is the same reason why WinProxy works with any kind of Internet connection. Windows takes care of redirecting all network traffic bound for the Internet to your Internet connection.

There are a number of steps you can take to make sure your firewall is secure. You do not have to do all of them but if you do implement all the steps you will have a secure firewall.

1. Use non-routable IP addresses for computers on your internal network (i.e. 90.0.0.1 - 90.0.0.254, with a subnet mask 255.255.255.0). Packets (information) from your internal network will NOT be routed onto the Internet. Even if a hacker breaks into your network he will not be able to send information back out.
2. In WinProxy, click on File => Settings => General. Make sure that the internal IP address specified is not the IP address for your internet connection. If there are multiple network cards on this computer check in Multiple IP Setup to make sure the external IP address is not included as an internal IP address. That way WinProxy does not think a user on the Internet is an internal user and will automatically reject any connections from the Internet.
3. Do not run any Internet applications that accept connections (mail server, web server, news server, etc.) because many will accept connections from both the Internet and your local network.
4. On the WinProxy computer, turn off 'File and Printer Sharing' on the external network card (Control Panel => Network).
5. Remove all networking protocols (NetBEUI, IPX/SPX, etc.) except TCP/IP from the dial-up adapter on the WinProxy computer. You can keep them on the internal network card.

Below is the information you will need for WinProxy's internal network card after you have added the TCP/IP protocol to it.

Your WinProxy computer's internal network card must be assigned a static (i.e. fixed) IP address. The IP address is a 32-bit address, subdivided into four fields. It is a binary number, but usually written in decimal form, e.g. 222.222.222.222. Each field can have a value from 0 through 255. However, since the end values are used for special purposes, the actual range available is from 1 to 254. In other words, when entering an IP address, use only members between 1 and 254 in the last field.

Associated with the IP address is the subnet mask. The mask tells the computer which part of the address is unique to the machine, and which part is the general network address. For most simple networks the subnet mask of 255.255.255.0 is the best and easiest choice. When you use this mask, the numbers in the final field of the IP address are unique to each computer and the preceding three fields define the network address.

The host name is the name you assigned to the WinProxy computer. (Each computer on your network should have a unique name). Avoid punctuation marks. If you do not know WinProxy's computer name click on Start => Settings => Control Panel => Network => Identification.

The domain name can be your ISP's domain name, but it is better to use our own. Feel free to make one up (e.g. fred.com, suzie.org). The name does not need to be officially listed with any Internet bodies- since it is on your local, private network. It is invisible to the rest of the world. All of your computers should have the same domain name, and because of the way DNS lookups are made it is best if you have a .com or other standard domain name on the end.

Your entry in this box should include:- (a) the IP address of WinProxy's internal network card, (b) your ISP's primary DNS server address, and (c) your ISP's secondary DNS server address.

Below is the information you will need for WinProxy's internal network card after you have added the TCP/IP protocol to it.

Your client computer's network card can either be assigned:- (a) a static (i.e. fixed) IP address, or (b) a dynamic IP address from the WinProxy DHCP server. Regardless of which way you go, the IP address of the client computer must be on the same network as that of the IP address assigned to the WinProxy's internal network card. For example, if WinProxy's internal IP address is 90.0.0.1 with a subnet mask of 255.255.255.0 your client computer should be assigned an IP address in the range of 90.0.0.2 to 90.0.0.254.

NOTE: If you have other subnets that you would like to go through WinProxy you will have to make entries within the routing table of the WinProxy computer.

The host name is the name you assigned to the client computer. (Each computer on the network should have a unique name). Avoid punctuation marks. If you do not know WinProxy's computer name click on Start => Settings => Control Panel => Network => Identification.

Enter in the IP address you assigned to WinProxy's internal network card.

This should be whatever name you entered for domain name in the WinProxy computer's internal network card, under DNS.
