Rick,

on your firewall's external interface, if there are packets arriving
supposedly originating from

- your LAN
- addresses from RFC 1918
- or those marked as 'reserved' in
www.isi.edu/in-notes/iana/assignments/ipv4-address-space

then either somebody is attacking you ... or there's a way besides your
firewall for packets from the LAN to leave...

I'm not sure if you meant this. Anyway,

regards,

Enno Rey

Ceterum censeo: everybody should implement network ingress filtering as
described in RFC 2267 on border routers...

Subject: ip addresses in lockup


is there a list of known ip addresses (or kindly share them with me
privately-thanks), that people think are just being used by
no-good-rotten-bad-people, and so they block them in their firewall? or
url's? like what?
