Layer 2 bridging on Mango Routers (Open WRT)

Hi, i’m trying for several days to do a simple (I hope) thing.

I need to bridge 5 Mango routers GL-Inet to link 5 network devices under the routers. I need a layer 2 bridge because this devices uses multicast to communicate.

I tried first to create separate subnets, EG:

  • NETWORK 1: 172.16.1.1
  • NETWORK 2: 172.16.2.1
  • NETWORK 3: 172.16.3.1
  • NETWORK 4: 172.16.4.1
  • NETWORK 5: 172.16.5.1
  • ZT MANAGED ROUTE set to 172.16.0.0/24
  • ZT MANAGED ROUTE set to 172.16.1.0/24 via 172.16.0.101 (IP address in ZT network)
  • ZT MANAGED ROUTE set to 172.16.2.0/24 via 172.16.0.102 (IP address in ZT network)
  • ZT MANAGED ROUTE set to 172.16.3.0/24 via 172.16.0.103 (IP address in ZT network)
  • ZT MANAGED ROUTE set to 172.16.4.0/24 via 172.16.0.104 (IP address in ZT network)
  • ZT MANAGED ROUTE set to 172.16.5.0/24 via 172.16.0.105 (IP address in ZT network)

From a zerotier client i can ping the devices behind the routers but for example NETWORK 1 i cant’ ping devices in NETWORK 2 and so on.

Next i tried to setup all the Mango routers in the same network (172.16.1.1) and use a different DHCP range eg:

  • NETWORK 1: 172.16.1.1 - DHCP from 172.16.1.10 to 172.16.1.19
  • NETWORK 2: 172.16.1.1 - DHCP from 172.16.1.20 to 172.16.1.29
  • NETWORK 3: 172.16.1.1 - DHCP from 172.16.1.30 to 172.16.1.39
  • NETWORK 4: 172.16.1.1 - DHCP from 172.16.1.40 to 172.16.1.49
  • NETWORK 5: 172.16.1.1 - DHCP from 172.16.1.50 to 172.16.1.59
  • ZT MANAGED ROUTE set to 172.16.1.0/24

but also this configuration in not working.

What I’m missing?

Thank you for the help, Marco.
