Using RA 6300 Security

Once the call is set up, a "session" between the remote device and

resources accessible through the RA 6300 port commences. The session

is maintained until terminated.

However, since the telephone network switch from which the PRI line to

the RA 6300 originates determines which ISDN B channel is assigned to

a internal port, static (i.e., port-speciﬁc) conﬁguration of RA 6300

internal ports is not possible.

For example, you cannot guarantee that a user connecting via a remote

PC will always use ISDN PRI B channel 9 and RA 6300 internal

asynchronous port asy12 every time the user connects through the

As a result, the RA 6300 relies on a set of parameters to conﬁgure each

port when performing the negotiations necessary to set up a call and

establish a session (i.e., dynamic conﬁguration). See Conﬁguring the PRI

Interface, Global Ports, and Sessions on page A-51, for more information.

For RA 6300 security, this means that security should be applied to

RA 6300 internal ports in global way (i.e., to all ports of speciﬁc type

(asy, ta, and syn)) applying security based on types of connections.
