IPTABLES and TFTP

Dru-Jitsu · 04-14-2011, 12:18 PM

So I am trying to boot with PXE. After obtaining an IP (from a windows server), it gets stuck at the TFTP and then gives a PXE-E32 TFTP open timeout. I have heard this is a firewall issue and have added all the ports to open, when I run an NMAP those ports still are not listening and I restarted the services and then the computer. After restart all the firewall changes I made are gone. I REALLY need help with this.

What distro are you using? How are you opening the ports? What service are you restarting?

This should open the port for you and save it.

iptables -I INPUT -p udp --dport 69 -j ACCEPT
service iptables save

iptables is probably not saving the settings that you are making. You can try :

/etc/init.d/iptables save

or

iptables-save

or

service iptables save
