Manage download traffic Internal(cache) Full Speed/Outside(Internet) limited.

Hi, hope this questions are in the right area if not please let me know.

We are a wisp, we have RB1100(Main)+RB800 over our network with ubiquiti equipment working.

The speed is manage by our radius server 1.5MB/1.5MB to each client.

Mikrotik has enable the hotspot for this, our network is working.

Now, we want to add a extra services to get a better navigation for our customers, is a cache called Thundercache.

The server is in test and working in our lab, now we need to add this extra server to our current production system for full test, we have some doubts we still don’t understand how to setup with mikrotik.

We want to know if is possible to detect the traffic, if the data came from our internal cache server(thundercache) give full speed to our client and if is from Internet limit to what radius say.

What are of mikrotik I need to learn to make this possible if is possible?

Any tip will be appreciated, thanks!!!
