Shorewall policies + rules


Wonder if anyone can help. I've just come over to Linux from Windows. I've been trying to configure shorewall and it seems to be up and running which is a good sign. The only thing is, it's running but it appears to be wide open.

I ran nmap against my box from another machine connected to the internet. I had quite a few ports in state open and certain ports were accepting connection requests. Not to secure eh

I have a policy to reject all from the net to the fw.
I've tried adding various rules also such as reject all from the net to a specified port on tcp + udp. But nmap still picks these pesky ports up as open and I can still connect to them

What am i missing?

maybe figure out what ports are opened, and close them specifically in the rules config file. Also, maybe you should find out why these are open in the first place - did a deamon open it? Maybe kill it.

Ah looks as if i've been having a blonde day!

Was concentrating on traffic coming from the net when as cuckoopint pointed out I need to stop the traffic going out from my box!!

All makes sense now.. DOH!

Thanks for the help
