Has anyone had any experience opening up non-standard applications on ports below 1024? I have a situation now that I need to open up port 502 on a custom application, however starting up the app as a root user and opening up the ports on iptables does not seem to do the trick. Below are my iptables rules and a lsof of the app running on 502. iptables -A INPUT -i eth0 -p tcp --sport $unprivports -d $ext_ip --dport 502 -m state --state NEW -j ACCEPT iptables -A OUTPUT -o eth0 -p tcp ! --syn -s $ext_ip --sport 502 --dport $unprivports -j ACCEPT listing of my iptables on port 502... ACCEPT tcp -- 0.0.0.0/0 192.168.0.2 tcp spts:1024:65535 dpt:502 state NEW ACCEPT tcp -- 192.168.0.2 0.0.0.0/0 tcp spt:502 dpts:1024:65535 flags:!0x17/0x02 Below is the lsof on port 502... COMMAND PID USER FD TYPE DEVICE SIZE NODE NAME reciever. 10273 root 3u IPv4 49966 TCP 2-0-168-192.example.com:custom_application (LISTEN) For some reason I am not able to access this port regardless that the firewall is open on the port. Am I missing anything here? -------------------- Brandon Spruth brandon@xolia.net
