Okay.

Okay. If pppd has not detached, then the SIGTERM will also be delivered
to your pppoe-server process. You must handle this signal.

Your observation matches.

I don't know. This is a question about pppoe-server and your current
source code. Are SIGINT and SIGTERM handled differently by pppoe-server
at different times? What version of pppoe-server source are you using?
I've just looked at rp-pppoe-3.8/src/pppoe-server.c and the signals are
both handled by exiting, in termHandler().
