Dialup security

mgeoghegan · ‎03-25-2002

We have a Cisco AS5300 with a PRI line that supports remote uses. We also use Cisco Secure ACS for authentication. I would like to know is there a way to secure the dialup connection of users who dial in via modem but also have a cable modem on there PC. I don't want internet users to be able to access our network via the users cable connection.

I don't fully understand the topology. Can you draw it out ascii style with parts of the addresses so we can see what is where? Sounds like you just need to put some traffic filters on there.

You could use ACLs to deny certain traffic from going to certain networks, or you could policy route traffic based on the source, to go out a specific interface...which should bypass the normal route which may want to go into your lan.
