Hello!
I have ER605 router and i need to connect it to OpenVPN server (Ubuntu Linux 20.04.6 LTS, OpenVPN 2.4.12). I have made setup of server and i have .ovpn file. It seems OK, because i can use this file to connect from my test PC, works fine. test PC in the same subnet(/24) with router, so it seems there are no network problems. But router doesn't want to connect. According to server logs there is a connection, cipher is ok, i even can ping router from server using it virtual address (in my case 10.10.0.2), but there is no connection, no data transfer, i can't ping server from router, and router doesn'r make tunnel. Router logs have ho information and are useless in this case (router is in stand alone mode).
My server config:
My .ovpn file:
My router setup:
Thank you!

Hi!
I spent one more day and found a "half-solution":
In fact router connects to VPN server and i can see it from server. After some routes setup on server i can connect to devices in router LAN at least for ping, web-interface(443/TCP) and BACNet(47808/UDP).
But problem remains, because router doesn't show tunnel and i can't do anything which needs interface from router inside (routing, NAT, etc). In my case it's not critical, but it's seems to be router problem, i hope TP-LINK can fix it in next firmware updates. It look's like not VPN engine problem, it's management software problem, which can't recognize existed tunnel.
I made some changes in previous configuration:
Updated OpenVPN server to ver. 2.6.8 (i read a lot of advices to downgrade OpenVPN, but they seems useless)
Changed auth to SHA512
Also keys was remade with EC/SHA512
Thank you for your advices.

So it is working now? But not displaying the tunnel, is that correct?
I got a reply from the dev and they told me that a beta may be provided if you need it. Let me know what you think.
