I'm pretty sure it won't be possible to do what I want to do, but I thought I'd ask the experts anyway...
We have remote users that dial-in over ISDN to a Cisco 2911. We have configured AAA to pass the authentication off to a RADIUS server. Once successfully authenticated, the router permits the users to access a single web server. This all works great.
However, we need to do some testing in our test environment, but unfortunately we don't have an ISDN line to test with. We have created a little environment in our LAB using a 2911, a switch, a RADIUS server & web server. I was hoping that we could simply create a "user" VLAN off the back of the 2911 to simulate our remote users, and access the web site from the test usr PC's over the LAN. I was hoping that the 2911 would be able to intercept the connection and pass the authentication off to the RADIUS server (as it does with the PPP ISDN traffic). But I cannot find anyway to do this, because I can only configure AAA to offload either PPP traffic or telnet/ssh connections to the router itself.
In summary what I want is for a user to access an internal web site over a LAN interface of a 2911 - but have the 2911 authenticate the user via a remote RADIUS server first. Is there a way to configure a 2911 (or any router!) to do this?
Is the answer to configure port-based authentication (802.1X) on the switch?
