Howdy 
 Been lurking here for a while to see if i couldn't pick up what i need 
  sigh .... 

 here are the problems 
with a few snippets from my logs & so forth
BACKGROUND:
we have two static portals (enough to deal with dns serving)
one is  firewall/dns/mail (zzzzzzzzzz)
other is dns / pptp(If i ever get it working) -- (I do this so i can muck
with it & potentially destroy it without having my "community" up in arms
..)

loging in from a NT box via phone modem and alternatly cable modem(pppoe)
(ssh connection with no problem) 
by phone - i get connected & auth.'ed but cann't get place beyond that (a
wins IS running) 
By cable modem - (this should eb easy - my home firewall seems to be
blocking ) get timeouts waiting for LCP 

pptp server is running RedHat 6.2 with 2.2.17 recompiled with the
appropreate patches from
http://www.vibrationresearch.com/pptpd/example.html

here is pptpd.conf
