Router RT-88AXU
I have used Merlin v384.19 OpenVPN server and have an OpenVPN client connection from my Synology NAS box (DSM v7). After upgrading Merlin to v386.3_2, the OpenVPN client connection from the Synology NAS box no longer can connect. After about a minute it says 'Connection failed. Please check your network settings.'. The ovpn file looks like this:

client
dev tun
proto tcp-client
remote XXX.XXX.XXX.XXX 1194
float
cipher AES-256-CBC
auth SHA256
keepalive 15 60
auth-user-pass
remote-cert-tls server
<ca>
-----BEGIN CERTIFICATE-----
-----END CERTIFICATE-----
</ca>
<cert>
-----BEGIN CERTIFICATE-----
-----END CERTIFICATE-----
</cert>
<key>
-----BEGIN PRIVATE KEY-----
-----END PRIVATE KEY-----
</key>
<tls-auth>
-----BEGIN OpenVPN Static key V1-----
-----END OpenVPN Static key V1-----
</tls-auth>
resolv-retry infinite
nobind

Any idea what could be the problem? OpenVPN connection from Windows work fine.

Thanks!

So many things (defaults) have changed between 384.19 and 386.3_2 firmware.

Can you simply reset the OpenVPN server on the router and re-create it following all known changes (see the changelogs since your previous version).

Thanks, it turned out to be a problem with the Synology NAS box. During Client VPN setup one needs to upload all certificate files explicitly rather than have them all included in the single ovpn file. There were no issues with the router. Merlin rocks!
