I have PF has a firewall with 4 jails and nat. I have the same configuration in a 6.4 with no issues. I can send you my pf.conf if you want and any dump file, just let me know with options do you need with tcpdump. I didn't have any offload stuff enabled I just install freebsd default, update to stable and start working, I didn't change any sysctl variable. The only estrange behavior that you can see that when a email is going to the deferred spool you will see a TCP kernel message just before that. Please let me know what you need to help me. Thanks.
