Update OpenVPN config on Unifi for AES256 - joshartman/Notes GitHub Wiki

Change certificates on a Unifi controller

The default OpenVPN encrytion is 128 bits and newer openvpn clients does not support this anymore.

It is required to login to the USG controller via ssh and update the openvpn configuration:

$ configure 
# show interfaces openvpn vtun64 
# set interfaces openvpn vtun64 encryption aes256
# commit
# save
# exit
$

The login credentials are found on the WebGUI page.
