NOTE


If you are using a one-way cable modem, you will need to have OrbitNet 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 OrbitNet can use to dial out.  You will, therefore, need to manually dial using the ISP's program, and enforce the hang-up yourself.  OrbitNet 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.


Internet Service Provider (ISP)

Below is the useful information you may want obtain from your Internet Service Provider (ISP).  Having this information beforehand will make OrbitNet'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.

Domain Name Service (DNS) Address(es) 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), OrbitNet can find the IP addresses.  In OrbitNet, click on File => Settings => Protocols => DNS Setup => Find_My_Name_Server!!
ISP's News Server Address 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".
ISP's SMTP (mail) Server 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.
ISP's POP (mail) Server 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.


Cable Modem

When using a cable modem, do not connect your cable modem straight into a hub.  Your cable modem should be connected to the OrbitNet computer.  This means that your OrbitNet computer will require two network cards.  One card will represent your external connection, i.e. your cable modem connection; the second card will represent your internal connection, i.e. your connection to your local network.  Also, if OrbitNet is running on an NT, we strongly discourage assigning more than one IP address to a single card. Both situations could expose your entire internal network to everybody else on your ISP's local node, as well as could give your ISP problems if there are other misconfigurations. Your ISP will be able to tell that you are running multiple computers, and they will require you to stop. We do suggest that you buy a second card, install it in the OrbitNet computer, and attach the modem to the second card. You'll probably have to use a cross-over cable instead of the standard one to make the connection from the modem to the card.

External Network Card on OrbitNet Computer 

Your ISP will assign you either:-
(a) 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
(b) a dynamic IP address, which means that your IP to your external connection will change every time you make a connection to the Internet.

OrbitNet works with both types of IP addresses from your ISP because OrbitNet is configured to use the internal network card that connects to the rest of your local network, so it does not matter whether your external IP address is assigned dynamically or is static.  This is the same reason why OrbitNet works with any kind of Internet connection.  Windows takes care of redirecting all network traffic bound for the Internet to your Internet connection.


Firewall (Security)

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 OrbitNet, 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 OrbitNet 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 OrbitNet 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 OrbitNet computer.  You can keep them on the internal network card.


Internal Network Card on OrbitNet Computer

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

Static IP Address Your OrbitNet 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.

Host Name The host name is the name you assigned to the OrbitNet computer.  (Each computer on the network should have a unique name).  Avoid punctuation marks.

If you do not know OrbitNet's computer name click on Start => Settings => Control Panel => Network => the 'Identification' tab.

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


Network Card on Client Computer

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

Static or Dynamic IP Address 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 OrbitNet 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 OrbitNet's internal network card.  For example, if OrbitNet'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 OrbitNet you will have to make entries within the routing table of the OrbitNet computer.

Host Name 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 OrbitNet's computer name click on Start => Settings => Control Panel => Network => the 'Identification' tab.

Gateway Enter in the IP address you assigned to OrbitNet's internal network card.
Domain Name This should be whatever name you entered for domain name in the OrbitNet computer's internal network card, under DNS.
DNS Server Search Order Your entry in this box should be the IP address you assigned to OrbitNet's internal network card.
