Tl-wdr4300-v1 without luci OpenVPN

Good evening, dear unknown networking fanatics.
I am building OpenWrt 19.07.3 r11063-85e04e9f46 (current stable) to fit (some might say cram) the packages[1] I need, but the resulting image doesn't show the luci-app-openvpn menu. I do need those packages to connect to an OpenVPN provider[2] and configure the remote access from the WAN to the the router's public IP.

  • If I download the firmware[3] from the device's page[4], install it into the router and then install[5] openvpn-openssl luci-app-openvpn via opkg, the web interface luci shows the "VPN --> OpenVPN" menu item.
  • If I build the firmware for v19.07.3 (with the corresponding options in menuconfig[6]), and install it into the router, the "VPN --> OpenVPN" menu item doesn't appear. Even after trying to install[7] openvpn-openssl luci-app-openvpn via opkg, the problem persists.

I have read this version's release notes[8], known issues[9], developer guide[11] and building frequent asked questions[12]. Rebooted the router from ssh, but the problem persists. Checked both bug-traking page, but I haven't found anything this issue in the openvpn-related[13][14] bugs.

It seems that I am building the ar71xx target instead of the ath79. I will give it a try to the ath79 build and post keep you updated of the results.

Thank you in advance for reading so far and for transforming limited propietary devices into powerful networking swiss-army knifes.
Any comments, thoughts and recommendations will be welcome.

I found a workaround. I built a new image without openvpn[15][16] packages. Installed the resulting image and manually installed[17] the conflicting packages. The problem persisted.

Finally, after installing vpn-policy-routing luci-app-vpn-policy-routing packages[18], the menu item VPN --> OpenVPN appeared. Also the menu "VPN-->VPN Policy Routing" shows now on the screen.

I built[18] a new image with all the needed packages (similar to previous[6] but with a new target) and installed it. The problem persist after manually installing the included openvpn packages[15] after manually installing the already included vpn-policy-routing packages[19], I can finally see the corresponding menu in luci.

After manually installing luci-app-openvpn and luci-app-vpn-policy-routing packages, It seems that they are being updated from the git repository.

Did I do something wrong? Is it a feature or should I create a bug report based in these observations?
