Package: iptables Version: 1.6.1 Severity: normal Dear Maintainers,
We found a weird bug: `iptables -L` will fail to parse this specific IP range 140.113.0.0/16 . It's incorrectly marked as "not-a-legal-address." $ iptables --version iptables v1.6.1 $ iptables -A INPUT -s 140.113.0.0/16 -p tcp -m tcp -j RETURN $ iptables -L INPUT Chain INPUT (policy ACCEPT) target prot opt source destination f2b-sshd tcp -- anywhere anywhere multiport dports ssh RETURN tcp -- not-a-legal-address/16 anywhere tcp $ iptables-save | grep 140.113 -A INPUT -s 140.113.0.0/16 -p tcp -m tcp -j RETURN However, this is definitely a valid IP range. 140.113.0.0/16 is the valid IP range in National Chiao Tung University in Taiwan. By the way, although it's incorrectly parsed, the rule still seems to work properly. Please let me know if you need other information. Thank you. Sincerely, bookgin
