Question / Problem:
What ports are used by the Message Connector?
Answer / Solution:
With the default configuration Message Connector uses the following ports:
- TCP port 25 – used for SMTP
- TCP port 25086 – used for Web interface between KC Plug-In and Message Connector
- TCP port 1720 – used for Fax over IP via H.323
- UDP port 5060 – used for Fax over IP via SIP
If other applications use any of these ports, you must change them in Message Connector configuration. Firewalls or virus scanners are known to block traffic on the ports, especially port 25.
