Hi all, I have two PPP interfaces on my machine which have different purposes and therefore need to have different pf rules associated with them.
In my pf.conf, I have rules that are specified based on ppp interface names (ppp0, ppp1). With pppd in linux I can force a specific interfaces to be used by specifying unit n in my /etc/ppp/options or simmilar; there doesn't appear to be an equivalent option in OpenBSD pppd. I have found (through experimentation) that pppd will always use unused ppp device with the highest number -- if ppp0 and ppp1 are created, but not up, then establishing a new connection will use ppp1 rather than ppp0. I can use this to some extent, but I would like the two PPP links to be able to go up and down independently of eachother and always get back the same ppp interface. Presumably there is another way to achieve this -- can someone point me in the right direction? Thanks, Nick
