Model: ER605 (TL-R605)  
Hardware Version: V2
Firmware Version: 2.2.3 Build 20231201 Rel.32918

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 @xiyingzi 

Thanks for posting in our business forum.

Local IP, what is your LAN?

Put the LAN subnet there.

You don't seem to get it. If you re-examine your config, you have a misconfiguration in Local LAN.

Would you please read it again and read it carefully? A very plain mistake in that.

Wireshark and paste the screenshot here. Mosaic your IP.

Use the filter to filter the port. I only need to see what happened to it as a VPN client.

After that some ping from my server (VPN IP 10.10.0.1) to router (VPN IP 10.10.0.2):

And got this:

But still no tunnel on the router:

my experience is that tp-link routers do not work as client on openvpn server 2.4 or later. when I have installed the openvpn server, I have installed for compatibility with older than 2.4 . , if I do not do that, the tp-link router does not work as a client against the openvpn server.

As there is no tunnel showing up but the ping is okay, can you let me know if the network is actually working or not?

If it is working, you might need to wait for a while before it shows up.

Network doesn't work:
1. I can wait few minutes and even few hours, nothing changes.

2. From server i can ping only router VPN IP (10.10.0.2) but i can't see router LAN devices (10.6.3.0/24)

3. On the router i can't do anything with this interface (as example NAT, firewall or routing rules) because router doesn't see it and doesn't allow me to set up this interface as option to other settings.

OVPN is supposed to be Client to Site instead of S2S. You might use this VPN wrong.

Can you confirm that your VPN server supports this S2S scenario?
