Hi
Which certificates need to be overwritten on the new router so that Openvpn clients can successfully connect with the certificate of the old router?
I have circled the suggested files in red, but I might be wrong, maybe not all of these files need to be overwritten.
Copy all the /jffs/openvpn/* content (or select just server1 or server2). Don't touch the /etc/openvpn/* content, this is dynamically taken from /jffs/openvpn/ when the server is launched.
