freebsd-stable@ is clearly the wrong mailing list and you do not give=20
enough details, either.  In order to debug this problem we need to know=20
the pf rules you (or pfsense in this case) are using.  In order to=20
operate with dynamic IPs you need to use the "(ifnX)" syntax - I'm not=20
sure if pfsense does this by default.  In addition there is a problem=20
with ppp under some circumstances that requires "(tun0:0)" in order to=20
fully get the IP update.
