[KLUG Members] Firewall rule question.

After upgrading to IPCOP, I have a _technical_ question
about it's ipchains rules.

I'm getting a log entry for rejected packet about every
two seconds.  Neither IP (source or destination) is mine.
I think it may be logging some kind of broadcast, like
dhcp, but I don't recognize the port either.

  I=0 F=0x0000 T=2 (#12)

My assigned IP from my ISP is in the 24.247.*.* range.

I know my ISP's DHCP server is running on a private IP
of 10.x.x.x.  (FWIW)

One thought I had is maybe IPCop is rejecting all private
IP address ranges from the internet, but I can't find
anything like that in the rules.

It seems to run fine otherwise, but any idea what would
be causing these entries?
