Hi i expect if packet is send to concrete virtual server on concrete port will be process within this server.
Ok. So it's not possible under FreeRADIUS v3, but you can implement something similar using unlang. * Add all your clients to a single virtual server * Write an unlang 'if' or 'switch' check using %{Packet-SRC-Port} * If your policy is simple, do the different things it as in-line policy. If it's complex, proxy internally to another virtual server e.g, something like: switch "%{Packet-SRC-Port}" { case "112" { update control { Proxy-To-Realm := VirtualServer } } case "113" { update control { Proxy-To-Realm := OtherVirtualServer } } } Note this is a bad idea for a couple of reasons: * All clients sharing an IP need the same shared secret * If you use a fixed source port, you can only ever have 256 requests being processed at once You're better off implementing NAT, and making sure every NAS has a unique address.
