My Prod servers are in my companies DMZ. What are the ports that needs to open in order to enable the master to do deployments to tentacle servers?
The Tentacle listens on port 10933 by default (you decide this when you install Tentacle), so you’d need to allow inbound connections to Tentacles on that port.
Alternatively if you set up your Tentacles in polling mode, they will make an outbound connection to the Octopus server on port 10943.
Both these ports are TCP only. The following links might help:
Hope this helps,
