Hello, guys
Right now I'm having an issue with a customer. He wants to point his DNS to umbrella but in a Guest Wireless. It sounds that it is easy to do, but the difficult situation I found is that the customer has to point to an internal server because of the internal CA when pre authentication occurs, and point to umbrella DNS when authentication is success. Because of it, we thought that making a change of vlan when post authentication it was a good idea, but we found that only Windows machines behaves good. It was not the same situation for Android and iOS. We considered mounting the umbrella virtual machine for doing this, but he has a license that does not support umbrella VM.
I will appreciate any help you can give me. Thank you in advance.

Hi Jason,
I know this is not a DNS forum, but as we all know, DNS is a very important topic in Umbrella. It's ok if you don't have the answer or if you don't want to waste your precious time here, but I think thare are better ways to respond. Thank you again.

Hi, Jason
Thank you for the answer. I had seen that post before but I'm a little confused because I'm not sure if it is the same issue I'm having, because our pre authetication portal is inside the customer network (obviously) and what we need is that when post authentication occurss, an endpoint have the umbrella for content filter. I hope you can understand me.

Hi, guys
The thing is that when doing the pre authentication we have to resolve the web auth url from inside, because there is no a public DNS register for that url, and the customer does not want to give the web auth with the IP address, instead of that he wants the url to be resolved by DNS. And when doing the post authentication, it is necessary to get the umbrella DNS IP addresses.. We don't know how to do it. I hope you guys can understand me.

Hi Jason,
Thank you for your answer again. Where can I configure that proxy? Is this configuration needs to be made in the L3 router on in the DNS server?. I think you are telling me to do something like this, aren't you? https://www.juniper.net/documentation/en_US/junos/topics/concept/dns-proxy-overview.html
