Numbers in /etc/sysconfig/iptables

Hello everybody :)

I have a doubt and I hope you can help me to make it clear. I wonder
what the numbers between the brackets in /etc/sysconfig/iptables stand
for, in example:

# Generated by iptables-save v1.2.6a on Tue Feb 25 10:04:19 2003
*nat
:PREROUTING ACCEPT [6892235:738030875]
:POSTROUTING ACCEPT [138782:15823395]

--to-destination 192.168.0.10:3389

[ ... ]

*filter
:INPUT ACCEPT [49677716:12655056270]
:FORWARD ACCEPT [7553652:3795256749]

ACCEPT
[0:0] -A RH-Lokkit-0-50-INPUT -d w.x.y.251 -p tcp -m tcp --dport 443 -j
ACCEPT

[...]

Most of these rules start with [0:0] and when I have to add a rule
manually I add it with [0:0] but I am not sure if that is the right
thing to do.

Can you help me with that or please point me where to read to find it
out?

Thanks!

Alex.
