Creating certificates and revocation lists using XCA.
Certificates overview
13.1
Any subscriber communicating over a VPN connection needs 2 certificates. One certificate must
be signed by a CA (Certificate Authority). Each subscriber must have the CA certificate plus a
“server” or “client” certificate. In our case:
The server
may be the
mbNET
or a separate server.
The client
is either a computer or another
mbNET
.
The certificates are required to set up a secure VPN tunnel and are used to authenticate the VPN
subscriber. If the subscriber has no certificate, or an invalid certificate, no VPN tunnel can be es-
tablished between the two devices if the authentication setting on the
mbNET
is
“
X.509
”.
