Tom,

Once again you prove you're a genius!

I was SOOOO close to getting it right. I already had the entry in the rfc1918 file, I had just added it to the end of the list, below the 192.168.0.0/16 entry, not above it.

Awhile back my cable modem started doing something different.  I'm on
Comcast and have a SURFboard cable modem.  Its IP address is
192.168.100.1.  Every 3 min. it sends out a broadcast message:

Feb 10 17:23:37 firewall Shorewall:rfc1918:DROP: IN=eth0 OUT=
MAC=01:00:5e:00:00:01:00:20:40:6d:d6:b7:08:00 SRC=192.168.100.1
DST=224.0.0.1 LEN=28 TOS=00 PREC=0x00 TTL=1 ID=0 PROTO=2

Whatever its doing (DHCP maybe?) I really don't care to see it in my
logs every 3 min.  I've tried various things to stop it, but I think
since its an rfc1918 address I'm looking in all the wrong places.

Bottom line, how do I turn off logging of this traffic?



This is a variant of Shorewall FAQ 14. Whereas in that FAQ, a RETURN
entry needs to be added to /etc/shorewall/rfc1918, in your case a DROP
is appropriate.
