I upgraded my RB2011 office router to the RB4011. I managed to transfer the configuration but I have a problem with certificates.
The router is used as an ovpn server for road warrior clients and I can't connect them back to the router. I get the following error from the client:
OpenSSL: error:14094418:SSL routines:ssl3_read_bytes:tlsv1 alert unknown ca
The ca certificate I used in the old router was self generated and I used it to sign client and server certificate
I exported them from the old server and imported them into the new (both .crt and .key file). However it does not seems to be enough. Is there a way to make the tunnels work with the old certificates ?
I tried to generate new certificates in the new router and the vpn works again but it's not usable in my case since I would have to change the certificates on all my clients.
Any help would be greatly appreciated
