- Fixing named private key command, not working in the latest version of Vyos
(tested with 1.4-rolling-g7c82c5c7104-20220217). It needs to be the private key.
- Updating the public key in the example to match the private key example, as
generated in the previous section.
- Explaining the persistent-keepalive flag in the RoadWarrior section

VPN. It just lacks the ``address`` and ``port`` statements.
In the following example, the IPs for the remote clients are defined in

the peers. This allows the peers to interact with one another. In
comparison to the site-to-site example the ``persistent-keepalive``
flag is set to 15 seconds to assure the connection is kept alive.
This is mainly relevant if one of the peers is behind NAT and can't
be connected to if the connection is lost. To be effective this
value needs to be lower than the UDP timeout.
