Our current access to the Internet is shown on the first line. We want to add a cable broadband link which also goes to the Internet as shown on the second line. On the cable link we want to allow a small subset of user pcs to surf through this link while still allowing the rest of the users to continue as before.
The edge router has two Fast Ethernet ports.
All equipment is Cisco brand.
PAT is performed at the PIX.
Is this a workable idea?
We are assuming if it is workable then some routing entries and ACLs would be made to the edge router.
Is there a better method to accomplish this? How?
