I'm currently using the following set up: https://openwrt.org/docs/guide-user/network/wifi/relay_configuration
I have a modem connected to the ISP (running stock fw), an TP-Link Archer C50 running openwrt connected to the main modem via WIFI and configured as a simple extender using relayd. This works great.
What I'm trying to achieve is connecting the openwrt router as an openvpn client and as a result, tunnel all traffic coming from client connected to it via ethernet. I followed this guide in order to establish a client connection:
https://github.com/StreisandEffect/streisand/wiki/Setting-an-OpenWrt-Based-Router-as-OpenVPN-Client and I suppose that client connection itself works (according the the status and system logs), though the connected clients are not passed through the tunnel. I suppose there's some additional configuration I'll need to do in order to associate the relayd interface with the openvpn interface, though I'm not really how. Can anyone point me in the right direction?
