AE system : what ports need to be open when using a proxy server?

[Legacy User]

I've  read from Proxy documentation and understood that one proxy client connects to only one proxy server.
What is your opinion?
For example, will we need 2300 port between any components or will we need like 2218,2219,2221.... etc ports?

The proxy server works as shown below:

> cpSelection = 0 (load balancing is disabled)

> cpSelection = 1 (load balancing is enabled)

Ports should be set like this:

To summarize :

• Agents need to be able to reach the proxy server.
• The proxy server needs to be able to reach the proxy client.
• The proxy client must reach the CPs.

The proxy server needs to be able to reach the proxy client.

Actually it is the other way round.
The Proxy Client connects to the Proxy Server and the CP's, that way you can place the agents into a DMZ without having to open the Network Area of the Automation Engine for incoming connections.

The only necessary connections between the DMZ and AE NW-Areas are between the Proxy Pairs and only in the Client -> Server direction, with configurable ports.

Hello,
Thanks for your opinion. I have a few questions more:
We need the port 2300 from Unix/windows Agent to Proxy Server and from Proxy Client to CP?
Is 8871 port number(for ServiceMaangerDialog) needed in any Proxy component?
Which incoming or outcoming ports needed for PDA (Predictive Analytics) to CP/Proxy Client/Proxy Server or AE DB ?
Another issue about Proxy is LoadBalance option. When I activate LoadBalance option, it is written in the docs UserInterfaces can not connect to CP. Proxy doc says that for UserInterface connections Proxy's Load Balance option must be disabled. So that, when LoadBalance option disabled, Components connecting this Proxy only connect to only one stated CP. However, when I test in our test envirenment and Customer side, Userinterfaces can connect to CP via ProxyPair whose LoadBalance option enbaled. Could you also check this issue about Proxy?
Another question is; Can we setup a few proxy server in same server usind different proxy ports?

Thanks in advance,
Oguz.
