How about the SCEP thing? The SCEP-speaking router would contact the RA

cert to the router?

no, i don't know which kind of router you use, but usally you can tell them if they talk directly to an ca or an ra - so they know there is step between


that means:
the communication beetween the scep-interface and the router/clients whoever uses the scep functionality is secured with the cert for this interface, which is signed by the ca too


the ca is always used to issue certificates - the ones for the ra, as for the route as for the clients - its always the ca who does this

Globally i just need a cert for the SCEP-speaking router and a way to
issue certs for the remote access users when they request them. Which
should be the "deployment view"? I know I can handle installation and
configuration issues, but I just don't see how it all would work
altogether.

usaly the whole administrativa is handeld at the ra-level, if one exists so there all the requests will get handeld by one ore more ra-operators even the request for the router - this works quite transparent actually

the ra-operator will see a request, maybe change this an that - than approve it, usally sign with its own cert, so the ca (ca-operator) can later verify who approved the requests

then those approved requests get exported (through an usb-stick, a tape, a disk, whatever) transported to the offline-ca - there you import the data through the node-interface (which actually handels the data export and import between the machines) and than the certificates gets issued there either manually or automatically through the batch system

then all goes backwards - export certs from the ca - import at the ra
when the certs are imported at the ra - they can be fetched by the users and also by the route through scep, of course it is possible that a user requests a cert through scep too - if his client supports this and so on, there are a lot of options, depending on your environment and needs and so on... ;o)


and don't forgett to issue a crl - i think the router at least will need one for proper operation - otherwise it could be difficult for him to decide if a certificate is really still valid or not

of course it is possible that this gets handeld all by one person ;o)
in larger szenarios this gets usaly devided, as there are technicans and people who decide who is allowed to use something - like the vpn-access - are different
