Network Requirements and Proxy Configuration for Promodag Reports
When configuring or operating Promodag Reports, it’s important to understand the network protocols and ports it requires, as well as how to configure proxy settings if your environment mandates their use.
Required Network Ports and Protocols
Promodag Reports does not use proprietary ports, but relies on several standard protocols.
All connections are initiated by the Promodag Reports console towards the domain controllers, Exchange servers and their file shares. Those systems never initiate connections back to the console, so you do not need these ports open bidirectionally. The traffic is one-way:
- On a network/perimeter firewall: permit console → target on the ports below. Reply traffic is handled automatically by any stateful firewall.
- On the host firewall of a target server (domain controller, Exchange server): the port is open inbound there.
- On the console's own host firewall: outbound only; no inbound listening port is required.
Port list
| Service | Port(s) | Direction | Target |
| DNS | TCP/UDP 53 | Console → target | DNS servers (usually your DCs) |
| LDAP | TCP/UDP 389 | Console → target | Domain Controllers |
| LDAP Global Catalog | TCP 3268 | Console → target | Domain Controllers (GC) |
| WinRM (PowerShell) | TCP 5985 (HTTP) / 5986 (HTTPS) | Console → target | Exchange servers |
| Network shares (CIFS/SMB) | TCP 445 (and 139 legacy) | Console → target | Exchange servers |
| EWS | TCP 443 (HTTPS / 80 (HTTP) | Console → target | Exchange servers |
For additional details about connectivity with SQL Server (typically TCP 1433) or Exchange Online, please refer to the dedicated articles covering those topics:
Using a Proxy Server During Configuration
If your environment requires internet access through a proxy server, you may encounter issues during the Promodag Reports configuration, especially if the application tries to connect directly to Office 365 instead of using the proxy.
To ensure Promodag Reports recognizes your proxy settings (as defined in Microsoft Edge or Internet Explorer):
- Open a command prompt as administrator.
- Enter the following command:
netsh winhttp import proxy source=ie
This command imports the proxy settings from Internet Explorer (or Edge) into the system’s WinHTTP configuration, allowing applications like Promodag Reports to use the correct proxy during configuration and operation.
