:OUTPUT ACCEPT [324693:28884726]

As explained here:

This contains a few comments starting with a # sign. Each table is marked like *<table-name>, for example *mangle. Then within each table we have the chain specifications and rules. A chain specification looks like : <chain-name> <chain-policy> [<packet-counter>:<byte-counter>].

So 328764 is the number of packets and 37367248 is the number of bytes.

Thanks. That mean I can set them all to zero when I use iptables-restore, right? – netvope Mar 14 '10 at 20:16
