Webdispatcher opening firewall ports
Hello All ,
We are facing a situation that our PI / SAP webservices are not reachable because of our systems being in MZ zones behind our corporate firewall.
I have looked for different options to make them accesable without compromising on security . The best solution i found until now is to use SAP webdispathcer.
But i am not clear on how it works. I get it that it must be installed in DMZ and it is the entry point for all Http communication , I am not sure how it talks to SAP servers in MZ .
Which protocol does it use ?
Are ny port need to be opened in the corporate firewall ( between webdispathcer & SAP servers )
If so which ones?
If the ports are opened , what big value is webdispathcer serving ?
Are there any other solutions for my problem ? (I already know about the AEX option ) .
Would be interested to know about your current topology and its advantages/disadvantages.
