Hi ilugd@lists.linux-delhi.org, I want to boot TFTP across my firewall (setup using iptables). I've blocked all UDP traffic except selective ones (which includes TFTP Port 69 also). Although I'm not good into networking in Linux but somehow I setup a firewall using Firewall-HOWTO.
The problem is I'm unable to boot my another PC via TFTP. The problems in TFTP protocol. 1. Client sends TFTP request to server on port 69 over UDP. 2. Server replies to client but from a different port (chosen randomly) say X over UDP. 3. And then subsequent TFTP requests from that client has to be sent to port X over UDP. Some articles are: http://www.firewall.cx/tftp.php http://www.unix.org.ua/orelly/networking_2ndEd/fire/ch17_02.htm http://www.google.co.in/search?q=tftp+firewall So, I don't want to open all my UDP ports. So is there any other way also ? Thanx in advance, Ashish Shukla alias Wah Java !! Wah Java !! -- Ashish Shukla "Wah Java !!" आशीष शुक्ला ,= ,-_-. =.
