Hi, I did use ipchains before. And now I start to use iptales. And already read howto, man pages and some other basic doc. I just met a problem that I cannot see the device info in the lists showed by iptables -L [-t nat]. Actuall I add the nic device info when adding a rule entry to it using -i or -o options. somebody can help me? I am eager to know it and some good doc you can index is also good for me. Thanks in advance!
