just as the title says. the log looks like this: port Source Protocol Service 80 <localhost> ICMP HTTP
is there something i can do to fix it? It seems that by setting the ICMP Filtering, no other rule can open it.
can't connect to MSN with Pidgin while using FireStarter and ICMP Filtering

Some things require ICMP. It does not surprise me that filtering all ICMP packets would cause something to break. It is allowed by default for a reason.
You could try creating a couple of rules in iptables, one to allow all outgoing ICMP packages and one allowing only incoming established ICMP packages.
The thing is that aMSN works while pidgin does not. and the only icmp i want to be allowed is the ones required by pidgin, how can i find what they are, and add them manualy to the iptables?
You could run wireshark to sniff the packets -- grab one of the packets and then choose the option to follow the stream. Usually that helps me figure out a lot of things.
Whats the deal with denying icmp anyways? Despite what others may feel, I dont think leaving your machine open to just pings is a security risk.
Solved, i just used a fork of the original msn plugin provided by pidgin. sudo apt-get install msn-pecan to get it. Homepage: http://code.google.com/p/msn-pecan/
