This article is from the Amiga Networking FAQ, by Richard Norman with numerous contributions by others.
What is TIA and Mlink, and are they useful to an Amiga User?
TIA ==> The Internet Adapter (TM)
by Cyberspace Development, Inc. (CSD).

It is a commercial software product that enables shell account users to have
partial SLIP access to the Internet without paying the extra monthly surcharge of
having a full SLIP account, and without having to have an Internet address. Since
TIA runs on the service providers host, Amiga users can take advantage of it too.
Although the service provider misses out on some revenue, they also miss out on a
lot of management headaches from SLIP. Check with your service provider to see if
TIA or Mlink is endorsed.
The drawback to TIA is that you don't have your own internet address, and
therefore no one can telnet or FTP to your machine. This does not stop you from
running Mosaic or FTP *OUT*. Just the incoming is unavailable. In other words you
can act only as a client not a server.
Another drawback is that you still have to have SLIP on the Amiga side. TIA
basically sets up a software gateway that speaks SLIP to your Amiga over the
serial port of the host, and TCP/IP over the host's ethernet card. TIA doesn't
allow the AmiTCP packets to pass directly to the Internet therefore your machine
has no address as far as the Internet is concerned. The Internet only sees the
service host. TIA makes the service host make TCP/IP requests on your behalf and
then passes you back the results. This does not work for some TCP/IP utilities
such as ping. Think of it as layers or stacks the data must filter through with
TIA as a middleman or translator.

There are well written docs available on line from CSD that explain TIA much
better. You can FTP them from marketplace.com. You can also use gopher and
Mosaic to the same site.
Mlink is available on Aminet and performs a similar function as TIA. It allows
you to use a cheaper shell account to access the Internet, but just like TIA it is
a one way glass: you can see out, but no one can see in.
