Hi guayc,
To confirm that I understand, you have some switches and a Fortinet as a default gateway, and want to use Fortinet to redirect users (wired/wireless) to a Captive Portal hosted at Extreme Access Control?
You have couple of options for Captive Portal redirection, the most generic ones are Policy Based Routing and DNS Proxy. "COS_40" sounds like the first one, and that's how it works:
- Your new client device walks through MAC authentication on a switch (EAC as a RADIUS server), due to NAC profiling rules it gets Unregistered policy.
- That policy, applied on a switch (could be some script or RFC3580-induced VLAN with relevant ACL applied to it) results in having TCP port 80 traffic marked with DSCP.
- When that web traffic (some HTTP request) reaches the gateway, it has an ACL for PBR that results in using NAC as a next-hop for that TCP 80 traffic with DSCP marking.
- NAC gets the request and takes over the web communication with a client device.
Please let us know if that's more less what you were thinking about.
Kind regards,
Tomasz
