Sounds like a routing/forwarding issue.

      * Have you enabled IPv6 forwarding? (sysctl
        net.ipv6.conf.all.forwarding)
      * As your rightsourceip addresses are part of leftsubnet, how does
        routing work? Do LAN hosts know they have to forward
        rightsourceip addresses over the gateway? (the farp plugin works
        for IPv4 only)
