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