Package: ppp
Version: 2.4.7-2+4.1
Severity: normal
Using ppp for the first time in a year or so, it seems something has
broken WRT defaultroute, which was working before.
There was no default route set before starting pppd.
After pon, this is the result:
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
0.0.0.0 0.0.0.0 0.0.0.0 U 0 0 0 ppp0
10.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0
wlx9cefd5fcd6f3
207.223.72.68 0.0.0.0 255.255.255.255 UH 0 0 0 ppp0
So apparently it's set a default route with no gateway, if that's even a
thing. It certianly does not work.
Manually adding 207.223.72.68 as the default gateway makes the connection work.
AFAICS I have no hook scripts or ifupdown configuration that would affect
ppp adding the default route.
I enabled debug and didn't see anything in the log about routing.
Here's the relevant part of the log, after authentication
(log is in reverse order)

Indeed, not a bug: this is a route to a PtP link, so it does not need
a next-hop.
