<![CDATA[routing traffic to LTE]]>What is the correct and easy way to route traffic to the cellular modem with the Omega2 LTE when there is no wifi?

Apn is set, 'o2lte data enable', got an ip address with 'ifconfig wwan0', i can ping from wwan0...

I disabled wifi on my router for the test and i can't connect to my mosquitto server with node -red or make opkg update or anything network related.

Thanks.

Sadly, it doesn't seem to be compatible with Onion's build. I hacked around this by modifying the default route of the Onion to whatever gateway the modem connects to for internet on the cellular network. I did not have the Omega2 LTE but rather Omega2 Pro with a modem connected via serial port (3g over PPP).

Is your mosquitto server on your local network? If it is then it's unlikely to be available when you're on LTE unless you have configured an external DNS and also you'll need some port mappings on your router, perhaps also firewall changes to permit incoming WAN traffic, since when you're on LTE you are effectively outside your local network.

Some other stuff to look at and let us know:

Try ping 8.8.8.8, if that works then it's probably a DNS issue, so try

nslookup yahoo.com

nslookup yahoo.com 8.8.8.8

If you get a valid response from the second but not the first then it's your DNS setup, check your /etc/resolv.conf for your name server.

If the ping doesn't work then it's a routing issue.
