The combination of FreeBSD pf and the FreeBSD port of relayd should buy you what you're looking for.

I believe the FreeBSD version of pf and relayd are close enough to the following tutorial assumptions.

You can drop CARP into the mix to get redundancy for the load balancer itself, i.e as a pair.

To be honest, it's simpler to just install a pfsense installation for the whole package though.
