we are using Extreme Control with two redundant NAC appliances. The radius part is working fine, but now we want to add redundancy for the guest registration web page, too.
Does anyone have experience with two redundant guest portals in Extreme NAC? Is this a valid setup anyway?
In the EWC we now have set up redirection to the IP of the first NAC portal. At this point DNS could be used to get the redundancy to point to both NAC portals. But I'm not sure if this works out as a whole.
