Could you please help with the clarification on the below?
We are in a process of installing Active gate in DMZ. Customer is saying, there is not internet connection to DMZ, and connection should be made through proxy.
Here, we want to understand
1. Firstly, if we are using proxy to connect to active gate, what is the need to install active gate in DMZ? We can directly connect through proxy.
2. Secondly, if we use proxy, SaaS will not be able to deploy anything as it one way communication from ActiveGate to SaaS
Please give us some detailed explanation on the above two. We are really confusing to understand the concept

1) Active gate is compresing data up to 70%. So you can have less overhead for network infrastructure. For Java and node.js applications active gate helps you with providing options for memory dumps. Another thing are active gate plugins that can be executed.
2) If there is no direct connection to cluster, you always have option of downloading binary from cluster locally and installing them by uploading to proper server. Your proxy settings has to have option not only for sending data to cluster on proper port. There also has to be communication with cluster on 443 to be able to download updates later.
Active Gate is really helpful in DT Managed because in such case we are not exposing servers via proxy to cloud, we are calling our local server. In such case you have only one network rule to make for active gate, not for all hosts in DMZ.
For me it is always better to setup things like proxy on single independent component like ActiveGate, not for monitored hosts. In such case monitoring should be independent of hosts creation, adding nodes, deployment etc. Connection is still established.
From your above comments what I understood, in case of DT Managed, it is better to setup proxy.
Please confirm in case of SaaS which approach is better. Below is the original question from customer
2 Options we have right now for ActiveGate Server.
Which one is best practice for
keeping ActiveGate servers in DC for OneAgent SaaS.
In addition to @sebastian k.'s answer to the 2) - communication is always unidirectional (agent -> activegate -> dynatrace server, either via proxy or not). Also, agents and ActiveGates maintain persistent connection, thus any configuration changes are propagated fast (typically within seconds).
