IPCop Log Traffic from Port Forward?

Wondering if there was anyway to log the traffic that goes through a
port forward in IPCop? I can easily see the failed attempts via the
logs but what about those which hit my special non-standard port and
reach my inside server? Is there any way to log this on IPCop or do I
have to log this on the server? The reason was, if I could do this on
IPCop, I could see everything at one location and easily banish those
IPs which I do not want accessing my internal server. Just an extra
layer of security. TIA.
