This topic describes how to disable the firewall so that PXE clients can download from the server. It includes separate procedures for SUSE Linux and Oracle or Red Hat Enterprise Linux.
Caution - Network security vulnerability. When you disable the firewall protection on your PXE server, the security of the data on that server cannot be ensured. If this server is networked outside of your local intranet, be sure to re-enable the firewall after downloading software to PXE clients.
