Guest portal redirect to hostname

[williamtan]

Hi Support,

I'm setup new guest anchor with foreign wlc and ISE recently. Guest are able to redirect the ise page with IP address, register and login without issue. But customer want to use hostname in the redirect url. The guest DHCP is getting from anchor wlc and DNS point to public DNS 8.8.8.8. Is it possible and how?

if you using 8.8.8.8 DNS it should be FQDN.

But how public dns resolve ise FQDN?
