3. Network connections and IP Addresses
3.1. Requirements
Servers are placed into the network so that a secure or reliable connection to mail servers can be made. Server requires one public IP address. This address acts as cluster address which e-mail traffic is relayed to. If NAT is used in address translation, information of both public and network address translated addresses is needed.
3.2. Options
• It is recommended that web-based management tool is separated from public network by defining D-Center with its own IP address and own port (default 443).
3.3. Firewall settings requirements
Firewall must allow the required connections. The following table shows requirements for basic installation; rules must be specified.
| Protocol | Port(s) | Usage |
|---|---|---|
| TCP | 1081 | Initial FQDN check, can be disabled post-installation |
| TCP | 80, 443 | Port 80 used for Letsencrypt, 443 for Http access |
| TCP | 3478, 5349 | Used by Turn server |
| UDP | 3478, 5349 | Used by Turn server |
| UDP | 40000-40500 | Used by turn server |
| UDP | 30300 | Used for the audio and video in conference |
