Message-ID: <51BCFB07.3060408@gmail.com> (raw)

Hello,

I have the following simpel stateless firewall... the issue is iam not 
able to send ICMPs queries from within the machine. What could I modify 
or add for this to be able to happen .  Also iam only intending to run a 
HTTP service and DNS service is it fine the way it is?

Also, I intend to keep the script stateless not wanting to use conntrack 
at all.

Thanks
Alex
