Zerotier on normal switch with OpenWrt

[plopes1960]

Hi all!

I have a ISP router and a openwrt switch.

ISP router network - 10.80.81.0/24
Zerotier network - 192.168.9.0/24
Openwrt switch - 192.168.9.200

This openwrt it's setup as a normal and regular dumb switch with wan and dhcp disable.

I have installed zerotier on him, and I can ping (trough cli) all the zerotier network.

I have put on Zerotier central managed routes:

10.80.81.0/24 via 192.168.9.200

However, from the pc that I have plug on this switch, I can't ping zerotier network.

Can anyone point me out what I need to do in order that from zerotier network I could acess to the network of this switch and reverse as well?

you're missing a static route on your router
192.168.9.0/24 via 10.80.81.x (LAN IP of device running ZT)

@AndrewZ many many many thanks!!!

I was looking everywhere on my openwrt switch, but than, after your reply, I went to my isp router and setup a static route and than voilá!!!

just one more thing @AndrewZ

from my pc on my local network dhcp range I can allready ping the entire zerotier network and all the managed routes.

I have put on Zerotier central managed routes:

10.80.81.0/24 via 192.168.9.200

However, from the reverse (from the ip’s on that managed routes) I can’t ping my openwrt switch… do I need to do anything else?

I'm not sure I fully understand your network topology. Will be good to see a simple diagram.
What's the source IP that cannot ping 192.168.9.200 ?

sorry my bad!

I had to reboot the 2 routers that have zerotiers on the remote areas.

Now everything works like a charm!

Once again, many many thanks!!!
