Need help urgently, thank you

yes

I can ping the LAN IP of the other router (ping in the router), but I can't Ping with PC. I think I may lack an iptables command or a route command

can you describe your setup... where is PC that you are trying to ping with.

The two sites use openwrt respectively. In openwrt, you can ping the LAN IP of each other, a: vpn ip 1.1.1.1 lan ip: 192.168.30.1 b: vpn ip 1.1.1.2 lan ip: 192.168.31.1

ok, following so far

In router a, Ping 1.1.1.2 is normal, and Ping 192.168.31.1 is normal In router B, Ping 1.1.1.1 is normal, and Ping 192.168.30.1 is normal

are the openwrt routers the default gateways for their respective lans?

But PC 192.168.30.141 under router a Unable to Ping 192.168.31.141 under B route

i assume you set up a netmaker network with the two routers and the netmaker server as nodes.

Both router A and router B have made export gateways,

can you provide the routing tables from the two routers and from a PC on the lan

好的

on the second router why is the default gateway 10.255.255.1?

10.255.255.1 is the gateway of Wan

your PC get their ip address/routes/dns from the routers via dhcp?

192.168.30. X is the network address range of LAN

need to see routing table from PC on lan

you need to turn forwarding on

Is the default option in openwrt

if you don't have forwarding on, packets will not traverse interfaces.

Thank you very much. The test has been successful. You can ping it. I'll restart the router and try again

???

（***** netclient pull）

I do not understand

Netclient pull will cause VPN network interruption. Can it only be performed manually?

a netclient pull is done at startup and then only if the mq broker cannot be reached.

The latest version of openwrt uses firewall 4. Is netmaker considering upgrading?

it has been discussed but no decision yet

Thank you again

your welcome
