Changing Port Numbers

Ports serve as endpoints for communicating with other devices. Typically, conventional port numbers are used for major protocols, but

devices that use these port numbers are vulnerable to attacks because these port numbers are well-known. To enhance security, your

Network Administrator may change the port numbers. When a port number has been changed, the new number must be shared with the

communicating devices, such as computers and servers. Specify the port number settings depending on the network environment.

NOTE

To change the port number for proxy server, see Setting a Proxy.

To change the port number for LDAP server, see

Registering LDAP Servers (MF8580Cdw / MF8550Cdn / MF8540Cdn /
