OVPN drops exactly every 60min with "wrong keyID 1" message

Wed Sep 27, 2023 5:05 pm

What could be the problem here? V7.12b9, imported .ovpn file:

/interface ovpn-client
add cipher=aes128-cbc connect-to=xxx.xxx.xxx.xxx mac-address=xx:xx:xx:xx:xx:xx name=ovpn-import1695809348 port=1080 protocol=udp use-peer-dns=no user=xxx
Code: Select all
13:53:21 ovpn,debug,error packet with wrong keyID 1, expected 3, dropping

It seems to be related to reneg-sec parameter, but I can't set it in the ovpn-file, the message "unsupported configuration parameter 'reneg-sec'" appears in the log.
This parameter can be set in Mikrotik's OVPN-server and even get exported since 7.11 Beta 7, so why it is not supported in Mikrotik's OVPN client?
OVPN documentation says it is available on both server and client. I have no access to the server, so I'm screwed 😞

You may want to contact support on this.
supout.rif will be needed as well so better to include it already in the ticket.

The OpenVPN client on MikroTik has the "reneg-sec" parameter disabled by default, meaning it is set to 0. I have noticed this in several tests I have been conducting recently because if "reneg-sec" is disabled on the server, it does not renegotiate the keys when the client is a MikroTik device; there is only the initial negotiation when the client connects.

There is also an important detail: even if you can set the "reneg-sec" parameter to 0 on the client, you would only be disabling key renegotiation on your side. If the server is set to 3600, renegotiation would still occur every hour, just as it is currently happening.
