    Do you have port forwarding set up?  Otherwise, how can A get past the firewall on the WNDR4300?

     

    I suspect there are two things working against you.

    1. WNDR4300 is performing NAT, so it's going to rewrite IP addresses.
    2. Stock firmware will only NAT IP addresses on its directly connect subnet.  In your case, it will not NAT 192.168.123.0/24 traffic.

    You should install DD-WRT on your WNDR4300.  Then you can disable NAT and operate it as a pure router.
