Hm - sounds like a broken peer to me; at least the kernel sync ppp
engines of NetBSD used to work with the legacy IP (IPv4) only peers
I've used in the past; only logging a warning. (Unless some other
parameter of pap and ipv4 negotiation is wrong on your side, too).
Our async PPP implementation has a workaround for broken peers: you can
disable ipv6 with "pppd -ipv6", but I didn't find such an option for
