I know nothing about IPSec VPN, so I can't help you any further.
You can add keyword "log" in to your block rules in pf.conf, start pflog 
(pflog_enable="YES" in rc.conf and /etc/rc.d/pflog start) and then watch 
with tcpdump which rule blocks your needed traffic and what next should 
be allowed / redirected.

Or you can ask some network / PF guru in freebsd-pf@ mailinglist.
