Hello all,

Can someone point me to documentation for reading the output of:

cat /proc/net/ip_conntrack

I'm having difficulty setting up a VPN client behind my iptables v1.2.4
firewall and would like to dig deeper. I've read Rusty's guides as well
as dozens of other documents, but none describe this command.

TIA,

Don Meyerson
