Hi Ansible community, I am working with Ansible AWX (24.6.1), and I need to understand the connectivity requirements for ports mentioned below. Specifically, I want to know if these ports need to be enabled bidirectionally or if unidirectional connectivity is sufficient. # System/Service Port(s) * * * 1 VMware vCenter TCP 443 (HTTPS) 2 Windows/Linux Servers TCP 22 (SSH), TCP 3389 (RDP for Windows) 3 PowerShell TCP 5985 (HTTP), TCP 5986 (HTTPS) 4 Network Devices TCP 22 (SSH) 5 Databases a) Oracle (Default) TCP 1521 b) MSSQL (Default) TCP 1433 c) Postgres TCP 5432 6 Active Directory TCP 389 (LDAP), TCP 636 (LDAPS) 7 Office 365 TCP 443 (HTTPS) 8 SMTP (Mail) TCP 25 Could someone please clarify this for me? Any insights or best practices would be greatly appreciated! Thanks in advance! Regards, Gowtham ---

AWX (and the worker nodes/execution nodes) needs connectivity to those targets, the targets do not need some type of reverse connectivity back to AWX, not even sure what that would be. If I understand you correctly, for your vCenter example, you’d submit or implement a firewall rule like: ```auto source | destination | dest port | dest protocol awx IPs | vcenter IP | 443 | TCP ``` This should give AWX connectivity to your vCenter. vCenter does not need to connect back to AWX’s port 443 if that’s what you’re asking.
