Enable packet routing from network interface eth0 to bridge interface
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ margin-bottom:0;
}
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.
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
10.3.100/24 10.1.200.21 UGSc 0 4376 eno1
...
The routing table on Ubuntu
Destination Gateway Genmask Flags Metric Ref Use Iface
10.1.200.0 0.0.0.0 255.255.255.0 U 0 0 0 bond0
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.

Did you try to set the gateway in your last line to the local IP address of br0?
