Heys fortytwo,
Welcome to the EAB, i am sure you will like it here..
as far as i know there are but few TCP/PPP / IP stack is
one is ANT (wich is no more if memory serves correctly but used to be VERY small), Genisis and AmiTCP 1,2 and 3
there is one that cames with a dongle.. from here
http://amigakit.leamancomputing.com/...3469e7e9d80700
the interesting and most important thing here is easynet, i have yet to find it elsewhere other than at amigakit.
If i had the time i would write a free tcp/ppp/ip stack wich you could specify an amiga port to its just a pain in the backside that you cannot specify a port to lump a tcp/pp/ip stack to... PC's can do it now.... its unfair
