Thanks Tim,
We mainly have Dell 7048p switch stacks - they do support an internal captive portal, however not external :(.
Remote sites have Cisco switches.
I was thinking of a couple of options as a possible workaround:
- inline bridging from the guest VLAN to a VM of some sort that can provide captive portal functionality, redirecting to the external ClearPass guest portal
- purchasing an Aruba Mobility switch, making it the L3 exit point from the Guest VLAN to provide captive portal (this approach would need an Aruba switch per site, though)
Any thoughts? Thanks!
