Configuring TCP/IP network

When configuring TCP/IP (transport configuration protocol/Internet protocol) each PC on the local network that will be required to access the Server will requires the TCP/IP network protocol is installed. For details on installing TCP/IP please see the information supplied with your PC.

 

Below is a quick guide to setting up a TCP/IP network.

 

 

Network IP addresses

On a TCP/IP network, each machine is assigned a number called its IP address. You can assign a name to the number by making an entry in a file. This file is named ‘hosts’ (note that it has no file extension). The file is located in the Windows directory on a Windows95 machine and in the system32\drivers\etc directory on a Windows NT machine.

 

An example of its contents is:

 

192.168.0.1 Server

192.168.0.1 mailhost

192.168.0.2 Client A

192.168.0.3 Client B

192.168.0.4 Client C

127.0.0.1   localhost

 

This has six entries for four machines. The entries for ‘Server’, ‘ClientA’, ‘ClientB’ and 'ClientC' specify the IP addresses that will be used to access machines with those names. The entry for ‘mailhost’ allows the server to be referred to both as ‘Server’ and ‘mailhost’.

 

The last entry ‘localhost’ is a special entry that allows the machine on which the hosts file is located to refer to itself as ‘localhost’.

Single PC

To access FTGate on a single PC you should add a ‘hosts’ file with the entries

127.0.0.1 mailhost

127.0.0.1 localhost

Network

This is an example of the most common setup in which FTGate is used.

It is recommended that a ‘hosts’ file be created for the local network, and that a copy is placed on each machine on the local network.

 

A single PC with a modem is used to connect to the Internet using either Windows 95 Dial-up Networking (DUN) or Windows NT Remote Access Services (RAS).

 

Internet Service Provider

FTGate Internet Connection

 

smtp.isp.com

 

newdomain.com

 

POP3 Host when SmartPop is to be used (this is where mail is to be retrieved from)

 

POP3 Mailhost : pop.isp.com

Account Name : newdomain

Password : pword

 

Server - PC running FTGate with the dial up connection.

 

IP Address: 192.168.0.1

Subnet Mask: 255.255.255.0

 

ClientA - Network Machine

 

IP Address: 192.168.0.2

Subnet Mask: 255.255.255.0

 

ClientB - Network Machine

 

IP Address: 192.168.0.3

Subnet Mask: 255.255.255.0

 

ClientC - Network Machine

 

IP Address: 192.168.0.4

Subnet Mask: 255.255.255.0

 

A ‘hosts’ file (shown above) would be placed on each machine. At this stage the network is ready for the Mail clients to be configured.
