I'm guessing IP changes are central to this question.
If so, configure your ruleset(s) using variables. For
example:
oif="ed0"
iif="ed1"
dns0="xxx.xxx.xxx.xxx"
dns1="yyy.yyy.yyy.yyy"
and possibly:
dhcp0="zzz.zzz.zzz.zzz"
...
Then, specify interfaces and IPs like ${oif}, ${iif},
and ${dns0} in your ruleset(s).
