To summarize what you wrote:
- synology includes a radius software, which is supposed to be freeradius
- you have no details on how synology implement their radius
- you want to use its bundled radius to authenticate cisco
Is that correct?
If so, then it seems that the only supported use of synology's radius
is whatever they tell you it can do (e.g. authenticate NAS users). If
you're using it for something other than its supported use, then
you're basically on your own.
Having said that, you might be able to perform additional
configguration on it if:
- you have no problem with potentially breaking (or voiding warranty)
your synlogy nas
- you have access to command line
- you are familiar with configuring software directly via command line
- you can read (and implement) the docs
As for "send radius attribute", if it were a normal freeradius
installation with mysql backend, and the attribute is specific to each
user, you probably need to add entries to radreply table, e.g.
However if you have only access to synology's GUI, and it does not
show similar option, and you don't have access to the underlying
database directly, then your best bet is to simply install a separate
freeradius server for cisco.
