I had tpl-mr3020 v3 with openWRT
It has 2 internet sources: wired from my main router and via 3g-usb-modem.
Also I installed tinyproxy on it.
In current situation when I am making request through proxy - request going through wired connection (through main router), but not through 3g-modem. I am checking it with whoer.net
I need next thing: wired connection can be used for local access (for example if I need connect to luci/ssh/proxy), but every connection to internet should go through 3g-modem.
I've tried some traffic rules but without any success.
Can someone help me?
