Are you sure Apache is listening on both IPs?

What netstat says?

# netstat -an | egrep 'tcp4.*80 .*LISTEN'

Also check what you have in httpd.conf for Listen directive

# grep -i Listen /usr/local/etc/apache24/httpd.conf

I am not using ezjail, I am using jail.conf

costa {
         host.hostname   = "costa.example.com";
         ip4.addr        = AA.BB.CCC.DDD;
         ip4.addr       += 192.168.222.57;
}

Real IP was replaced with AA.BB.CCC.DDD

And it works. Services inside jail must be listening on both IPs or 
wildcard * (0.0.0.0)

And be sure to disable hosts services to listen on IPs and ports you 
want to be served from jail.
