How do you access nodes through over tap-bridge over Linux bridge?

[Nato Morichika]

I have a set up like this:

Layer 2 Topology:

                 [ linux ]        

                 +------------+

[ node 2 ]       | bridge     |

[ tap-bridge ]---|-[ tap ]    |   [ lxc container ]

                 | [ vm-tap ]-----[ eth0 ]

                 +------------+

IP addresses:

tap-bridge: 10.1.3.1/24
bridge: 10.1.3.2/24
eth0: 10.1.3.254/24

I am trying to access 10.1.3.1 (on a CSMA net device of Node 2) from inside of the LXC container, The Node seems to get the ICMP packet from LXC, but it did not send any ICMP reply. 

Here are some logs I gathered from ns3:

It seems to be working, but nothing actually being sent.
