Macvlan no ping possible

Installing and Using OpenWrt
1

Hi,

i tried to use macvlan to have multiple interfaces on my lan ports.
I plan to use mwan3 as i want to combine 5 gateways that are all on the same physical network.

When i define 2 additional interfaces, i can ping them locally on the router but i'm not able to ping other devices connected via the lan ports.

Anyone here can help me?

I guess you should use the same ifname=eth1.1 for interface=lan and device=veth*.
On the other hand, you can set up multiple LAN interfaces by spliting VLANs.

Thanks for reply!
if i use ifname=eth1.1 on the veth interface, it disappears in ifconfig...thats annoying because the sample confings i've found also say that i should use eth1.1 instead of eth1

VLAN is not possible because i have one huge network (physically a few kilometers, connected via directional wifi) where the gateways are located.
