as root: iptables -vnL

as user you may look at some files. They are indicators... interpret 
them. I don't know how to get the rule set.

$ test -d /proc/sys/net/ipv4/netfilter

get info from /proc/sys/net/ipv4/netfilter/* and /proc/net/ip_*

look for logs
$ dmesg | grep 'IN=.*OUT=.*SRC=.*DST=.*'

gentoo: specific
$ /etc/init.d/iptables status
$ test -s /var/lib/iptables/rules-save

Sascha.
