Man, this is the second question that I've posted to the list that I
eventually answered myself....some help you guys are ;).
Anyway, just for future reference what the deal is, is that some Mac
dial-in programs such as FreePPP have an option to check whether a PPP link
is up by sending out a LCP_ECHO_REQUEST (LCP options are some of the lower
level PPP things you see when you set debug to 0x51) after a configurable
amount of time. Our other Mac customers were sending the LCP_ECHO_REQUESTS
and getting LCP_ECHO_REPLIES in response, but for some reason the
portmaster couldn't send the reply to this particular ISDN customer.
To make a long story short, I walked through this guy's settings over the
phone and found that there was a "Echo" option that was set to send every
20 seconds, we turned that off and the problem was fixed.
