I have a Fedora 3 core 86_64 box running with this rule set as generated by the fedora firewall bring up. Eth1 is a trusted interface, and is the private network. dhcp runs find, and returns a file name, yet tftpd does not run, getting a port rejected. I have two ethernets in my box. 10.0.0.1 and a.b.c.d. the 10.0.0.x is the private network and the a.b.c.d is my public network. Everthing works fine except tftpd which gets this error 08:45:49.945234 IP 10.0.0.10.2593 > 10.0.0.1.32819: UDP, length 4 08:45:49.945261 IP 10.0.0.1 > india10: icmp 40: 10.0.0.1 udp port 32819 unreachable 08:45:52.612474 IP 10.0.0.10.2593 > 10.0.0.1.32819: UDP, length 4 08:45:52.612521 IP 10.0.0.1 > india10: icmp 40: 10.0.0.1 udp port 32819 unreachable What rule set do I add so that ports on eth1 above 1024 will be accessable on eth1 and tftp will work?
