You can try keeping up-to-date version of /etc/hosts with hostnames of
public services pointing to you 127.0.0.2+ IPs. It's dirty, but at least
keeps your pf.conf clean as much as possible.
It works for me and it should for you if you dont move services around a
lot. Then it requires lots of recursive changes in each jail if you move
some service from one IP to another.
