This was happening because ppp was deleting then re-adding the interface address when IPCP came up, causing the new routing code to nuke the static route. I've added an optimisation to stop this from happening, so your configuration should work ok again with src/usr.sbin/ppp/iface.c 1.17. > > -- > > Andrey A.
