How about some logs?

When dealing with internet connections there is always someone/something scanning for open services, people who use dynamic connections will see the leftover packets hit their firewall from previous connections, and just people who pointed to the wrong address.

Currently with the rpc worms there is constant attempts for inbound icmp type 8, and tcp/udp 135. The more common probes are the netbios ports of 137-139, recently ports 1026-1027, and various other ports.

So just calm down, somebody is not out to get you personally, its something that comes with the internet.

I'll say this straight up, the logs in Outpost suck, and there is no ICMP (2048)....

This is part of the welchia worm, it pings(icmp 8, echo request) you first, and if you answer the ping by sending icmp 0 echo reply it will then see if it can connect to your system on port 135. However eariler versions of the worm only sent packets to your port 135. Even if you allowed the pings they won't hurt you, and your blocking the port 135 probes so your fine.

So, you can either ignore the logs, or hopefully through the settings block it without logging it if its bothering you so much. You would have to make a rule to block inbound icmp type 8 echo request, and not log the packet. I don't fully remember how to tell you how to do that, but it would likely be part of your system rules.

Everyone is seeing this right now, your not special, and the worm does this on the same ip block that the infected computer is on.

Outpost is one of many known software firewalls with horrible logs, but I was hoping they had actually gotten a clue about it. If they want to be taken seriously from an advanced security standpoint they better have detailed logs.

OT: I have tried many firewalls, and one of the main things I judge is the logs. In the rare event I report something like a real attack/flood to disable my connection then I want logs which the abuse desks which won't just read the first line realizing that they are useless, since they are missing information.

Well it was kinda weird cuz right when I switched to Outpost I started getting these. I usually use sygate, but I wanted to test a bunch of firewalls out there. I liked Mcafee's interface the best, but I still think sygate is the best firewall.
