There is the follow question in FAQ on netfilter.samba.org 3.7 How do I list all tracked / masqueraded connections, similar to 'ipchains -L -M' in 2.2.x ? The answer is: cat /proc/net/ip_conntrack Ok. Is it similar? When a "cat" /proc/net/ip_conntrack I got only IP while ipchains -L -M I got resolved IP names. There is a way to do really similar thing in iptables?
