I have a Ubuntu server connect to LAN 10.1.200.21/24 (bond0), and an Macbook connect to LAN 10.1.200.50/24 (eno1)
There are another bridge create by brctl addbr br0 in Ubuntu 10.3.100.1/24, and there are three VMs connect to that bridge.
This picture show the entire network topology
My question is how to access those VMs 10.3.100.x/24 from my Macbook 10.1.200.21?
The routing table on Macbook
Destination Gateway Flags Refs Use Netif

...
The routing table on Ubuntu
Destination Gateway Genmask Flags Metric Ref Use Iface

10.3.100.0 0.0.0.0 255.255.255.0 U 0 0 0 br0
...
I can ping those VMs from my Ubuntu server. However, when I try to ping VMs from Macbook, the packet only send to bond0 on Ubuntu, but not routed to br0 (tracked by tcpdump).
Besides, I have enabled net.ipv4.ip_forward = 1.
