====== Communication Ports ======
----



**Xcalibur W** generally operates under two scenarios: a local LAN environment and a routed WAN environment.


**Xcalibur W** can and will operate successfully on port 443, but in order for **Xcalibur W** to operate to its full extent, a number of other ports should be opened.

These are :


^  ^  ^  |
|Pulse over **LAN   & WAN**  |TCP 443 |Client **=>** Server |
|Discovery over **LAN only**  |TCP 9999 | Client **<=** Server |
|Pulse synchronization (**LAN only) **  | TCP 7270 |Client **<=** Server |
|Remote Assistance (Reverse VNC) |TCP 5980~89 |Client  **=>** Server |
|Software Distribution (Peer-to-Peer) |TCP 8080 |Client **<=** **=>** Server |


|


|{{:tip.png |}} These ports are the default ports used when **Xcalibur W** is installed. If necessary, these ports can be modified in the Agent Configuration, Manager Options, and Discovery Options screens.|**\\
