Hi!
There is a bug in pppd-2.3.5 which was patched in later
pppd releases but wasn't included in FreeBSD. When you use '*'
as IP address wildcard in a secret file then pppd is trying to
gethostbyname() for '*' as domain. Because no external route
available the gethostbyname() call timed out, but pppd is
timed out before, and PAP auth failed.
You may use this patch to pppd/auth.c to fix the problem:
