Hi all,
I can't get the OpenVPN to work properly anymore. Does anyone see the mistake or know the trick to get it to work?
RUTX10 - OpenVPN Server Config
- See screenshot
- RUTX10 DHCP enabled and is working for local connections (wired and wireless). Internet connection also works.
- Router IP: 192.168.14.254

2021-07-29 14:48:04 DEPRECATED OPTION: --cipher set to 'AES-256-CBC' but missing in --data-ciphers (AES-256-GCM:AES-128-GCM). Future OpenVPN version will ignore --cipher for cipher negotiations. Add 'AES-256-CBC' to --data-ciphers or change --cipher 'AES-256-CBC' to --data-ciphers-fallback 'AES-256-CBC' to silence this warning.
