Question

What are the recommandations when Automator servers (production and/or modeling) have to communicate through a firewall ?

Which TCP and/or UDP ports should be open on the firewall ?

Answer

All the TCP and UDP ports used by the Automator servers that will communicate together should be opened on the firewall.

Example:

- On one side of the firewall, we have one Modeling Server MS01 (TCP 10500 / UDP 10501 & 10502) and one Production Server PS01 (TCP 10510 / UDP 10511 & 10512). On the other side of the firewall, we have one Production Sever PS02 with different ports (TCP 10610 / UDP 10611 & 10612).

- MS01 will necessarily communicate with PS02, so at least, all the TCP & UDP ports of MS01 and PS02 need to be opened on the firewall.

- If PS01 and PS02 have common instances, they will communicate together, so all the TCP & UDP ports of PS01 also need to be opened on the firewall.
