Connecting IMS MAIL to the Internet.
There are many ways of connecting computers to the Internet, these include the following methods:-
Non permanent connections:-
 | 56k Modem or an ISDN terminal adaptor and using a “DIAL UP ACCOUNT” with an ISP (Internet Service Provider) |
Permanent connections:-
| Cable modems (up to 512k). |
| Leased line (up to 45mb) |
| ADSL |
NOTE:-
IMS MAIL does not ROUTE TCP/IP traffic to the Internet, it
needs this to be provided by an external system, some of the possible solutions
to this are the following:-
LINUX
ROUTER
Attaching a LINUX system to the
network and using this to route the network TCP/IP traffic, connecting using one
of the following methods:-
| 56k Modem or an ISDN terminal adaptor and using a “DIAL UP ACCOUNT” with an ISP (Internet Service Provider) |
| Cable modem |
| ADSL |
| Leased line connection |
Microsoft Windows 98SE (Second edition) acting as a router
Attaching a Windows 98SE system to the network and using this to route the network TCP/IP traffic, connecting to the internet by using one of the following methods:-
| 56k Modem or an ISDN terminal adaptor and using a “DIAL UP ACCOUNT” with an ISP (Internet Service Provider) |
| Cable modem |
| ADSL |
Microsoft Windows NT/2000 Server acting as a router
Attaching a NT/2000 Server system to the network and using this to route the network TCP/IP traffic, connecting using one of the following methods:-
