Does anyone know what ports need to be opened up when using TFTP to configure Cisco phones? The configuration below doesn't seem to work. However if I open everything up the files comes down just fine. iptables -A INPUT -p udp -s 0/0 --dport 69 -j ACCEPT Thanks for your help! Chad
Hi Chad, It should be sufficient. Try logging the blocked traffic. iptables -A INPUT -i eth0 -s 0/0 -j LOG On Thu, 5 Aug 2004 21:46:25 -0700 "Chad Brown" <chad.brown@identitymine.com> wrote:> Does anyone know what ports need to be opened up when using TFTP to > configure Cisco phones? > > The configuration below doesn't seem to work.
