Hi Javier.
What you described is essentially what I did - that being that I simply
changed the declaration of:
ext_if = "tun0"
to
ext_if = "pppoe0"
(which is located at the very beginning of my pf.conf) and that was it.
It works perfectly. Perhaps you have one or more lines with literal
references to tun0 (whereas it/they should instead be to $ext_if) in
your pf.conf?
Mick.
