"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

The alert indicates the firewall's seen traffic with a source address of 127.x.x.x. Usually, this is someone trying to exploit local host rules on the firewall.

The firewall's correctly blocking the traffic. If it's appearing on an internal interface, you should check the MAC address and track down the culprit.

If it's happening on the external interface, you should pass this info on to your ISP, since they shouldn't be routing this traffic to you.

If it's happening on a wireless interface, lock down access (WPA2). If that's already done and you're using a pre-shared key, it's been compromised.

In all cases, the firewall's doing its thing and blocking the traffic.
