dns interceptors

Not familiar with --outform argument. Will have to look into it.

Presume you are doing site to site/network to network? Or are you setting this up for end users to terminate to?

I've done the latter many many times, but not net to net. Happy to provide docs if you/nanog like.

I think that everyone should run a vpn to secure remote access to services they are operating.

You integrating this with an existing ski infrastructure? If so is it openssl based?
Or maybe ad based?

Lots of openvpn variables.... Might be worth starting a new thread on the subject. As I said, I feel its vital for folks to have a deep familiarity with openvpn and best practices etc.

end user to network

having probs with certs, i.e. what --outform it wants. not finding in
docs. tried raw, but now guessing pem. same for client and server

server
  ca.crt
  server.crt
  server.key

client
  ca.crt
  client.crt
  client.key

and i presume i have to dump all client.crt files in the server's
../openvpn dir, but under what names? or does it just wantonly trust
anyone under that ca?

What error is getting logged?

They are just normal cert's and should be in the keys directory under openvpn's user directory.

OpenVPN includes scripts that can make the certificates for you under the directory easy-rsa

Use the easy-rsa stuff and it will do all the hard work for you.

Randy,

pem format.

Any cert signed by that CA. Use --cclient-config-dir to limit which CNs are acceptable, and to add custom configs per client on the server. On the client, use --tls-remote to limit which CN the client will accept when connecting to the server.

On the server, you can also roll your own script to inspected the certificate presented by the client, and act on that.
