Iptables output is not showing any connections

[James McKenzie <jjmckenzie51@xxxxxxxxxxxxx>]

All:

I addes ports to my firewall using system-config-securitylevel and now 
the output of iptables -L -n -v shows the following

Chain INPUT (policy ACCEPT 104 packets, 25577 bytes)
pkts bytes target     prot opt in     out     source               
destination

Chain FORWARD (policy ACCEPT 0 packets, 0 bytes)
pkts bytes target     prot opt in     out     source               
destination

Chain OUTPUT (policy ACCEPT 132 packets, 8235 bytes)
pkts bytes target     prot opt in     out     source               
destination

Should it not show available connections and what they are doing?

Thanks.
