Network ports are configured during the Update Manager installation. After installation, you can only edit whether to use an IP address or host name for the Update Manager patch store.

Use an IP address whenever possible to avoid any potential DNS resolution problems. If you must use a DNS name instead of an IP address, ensure that the DNS name that you specify can be resolved by all hosts managed by Update Manager and by vCenter Server.

You can change the ports by editing the vCenter Server system configuration. For more information, see "Edit the Settings of Services" in the vCenter Server and Host Management documentation.
