[ydl-gen] Question about NAT

[hFusion]

Hello, I recently installed YDL 4 on a Power Mac 7300 thanks to 
shiner.info.  I was able after numerous google searches to setup a 
temporary NAT using my external serial Global Village modem.  I say 
temporary because I have not found any Howtos describing how to setup a 
PERMANENT NAT.  I have to manually start the NAT server every-time the 
server restarts.  More, even though I have it setup in the Network 
preferences to automatically redial when the PPP connection is dropped, 
it is not.  In fact, I have to restart the computer before I can get 
the modem to redial.  (I was, however, able to get it to automatically 
connect during boot-up).

Basically, I'm not asking necessarily for a step-by-step manual be 
given to me here, but maybe just anyones thoughts on the problems I 
described above and possible a link to a good already published 
step-by-step guide that is still relevant.

Thank you very much in advance :).
