17.2 Configuring the Fedora 31 Firewall to Allow NFS Traffic

Next, the firewall needs to be configured to allow NFS traffic. To achieve this, run the following firewall-cmd commands where <zone> is replaced by the appropriate zone for your firewall and system configuration:

# firewall-cmd --zone=<zone> --permanent --add-service=mountd

# firewall-cmd --zone=<zone> --permanent --add-service=nfs

# firewall-cmd --zone=<zone> --permanent --add-service=rpc-bind

# firewall-cmd --reload
