Hi there,

I'm trying to get a OpenVPN to work on my ER707-M2 router in controller mode. In order to do that I've done everything this guide says: https://www.tp-link.com/ae/support/faq/3633/.

However, when I try to connect my laptop to the VPN using the generated OVPN file, I get the following error (redacted my IP address):

Thu Sep 19 11:01:21 2024 DEPRECATED OPTION: --cipher set to 'AES-128-CBC' but missing in --data-ciphers (AES-256-GCM:AES-128-GCM:CHACHA20-POLY1305). OpenVPN ignores --cipher for cipher negotiations.

Thu Sep 19 11:02:21 2024 SIGUSR1[soft,tls-error] received, process restarting

When I port forward 1194 to another port on my pc, it seems to work. This rules out the ISP blocking that port. There is no modem from my ISP involved, I use the ER707 directly.

I've also tried PPTP, which works. However, I can't get IPSec to work either.
