Chapter 5. Modifying firewall rules
5.1. Modifying firewall rules for disk encryption
On Network-Bound Disk Encryption (NBDE) key servers, you need to open ports so that encryption keys can be served.
Procedure
On each NBDE key server:
Open ports required to serve encryption keys.
NoteThe default port is
80/tcp. To use a custom port, see Deploying a tang server with SELinux in enforcing mode in the Red Hat Enterprise Linux 8 documentation.# firewall-cmd --add-port=80/tcp # firewall-cmd --add-port=80/tcp --permanent
Verify that the port appears in the output of the following command.
# firewall-cmd --list-ports | grep '80/tcp'
