ipcop support

In firewall rules, underneath some of my port forwarded ports, there is a bolded black line that says 'IPCop External Destination: Red Address : xxxx' where xxxx is the port forwarded port. Some of the lines do not have this. They all port forward from red to green.. a couple are to orange. Why are some missing the 'External Destination: Red address' message? It's looking like the ones that don't have this message have the same internal and external port (not actual source port but you know what I mean.. I.e 80->80). But I just want to make sure.

Thanks
