Subject: [Asterisk-Users] TFTP Secondary Ports

I’m publishing tftp through my firewall to support external Cisco 7960 sip phones. I know that the primary port is 69 for tftp. However, tftp also uses secondary ports ranging from 1,0XX to 30,XXX. ( A broad range) In an effort to limit the secondary ports that are opened, some Windows based tftp server such as the winagents product allows you to limit the range of secondary ports that are used allowing you to somewhat tighten firewall publishing rules.

 

Does anyone know how to do this using the linux tftp server?

 

Thanks, Chad
