5. Change default WebADM listener Ports

The proper way to change a WebADM default lister port is by creating the /opt/webadm/conf/webadm.env file. In that file, you can configure the following settings:

# Interface used
INTERFACE=1.2.3.4

# Apache standard port 
HTTP_PORT_STD=1080

# Apache SSL port
HTTP_PORT_SSL=1443

# Web Service standard port
SOAP_PORT_STD=2080

# Web Service SSL port
SOAP_PORT_SSL=2443

To take into account these changes, you have to restart your WebADM server(s).

If you need to change the PKI Server Port then follow this documentation RCDevs Hardening Guide - 7.2 Change Port.
