Read it's man page:
http://www.freebsd.org/cgi/man.cgi?query=rsync&apropos=0&sektion=0&manpath=FreeBSD+Ports+4.7-RELEASE&format=html

you can do this at the firewalled machine
(examples only, not real commands) :
rsync -u [EMAIL PROTECTED]:file file
rsync -u file [EMAIL PROTECTED]:file

This will guarantee that file is the same on both machines.
