= Configuring network firewalls for {brandname} traffic

Adjust firewall rules to allow traffic between {brandname} Server and client applications.

.Procedure

On Red Hat Enterprise Linux (RHEL) workstations, for example, you can allow
traffic to port `11222` with firewalld as follows:

[source,options="nowrap",subs=attributes+]
----
# firewall-cmd --add-port=11222/tcp --permanent
success
# firewall-cmd --list-ports | grep 11222
11222/tcp
----

To configure firewall rules that apply across a network, you can use the
nftables utility.
