I followed all of the instructions at EasyTether - GL.iNet Docs and was able to install easytether-usb from the 19.07.3+ drivers. Everything works other than the update to /etc/config/network to add the extra wan config for tap-easytether disappearing after reboot. I fixed that by modifying the existing ‘wan’ config to use ifname ‘tap-easytether’ instead of ‘eth0.2’.
Everything seems to connect – the phone says Connection Established, I see the device at 192.168.117.2, and I see some traffic flowing on the tap-easytether interface. However, my internet browser can’t go to any sites (“ERR_CONNECTION_REFUSED”), and on the router I can’t ping any internet sites – names seem to get resolved to IPs, but all of the pings fail.
Any suggestions? In the logs I see “Apr 17 06:26:00 2021 daemon.info dnsmasq: using nameserver 192.168.117.1#53”, but when I try to ping that IP I don’t get any response.
