I don't run a firewall at all from linux but do have a Netgear switch/router/Firewall upstream between me and the internet cable modem. Output of iptables -L: reader > sudo iptables -L Chain INPUT (policy ACCEPT) target prot opt source destination Chain FORWARD (policy ACCEPT) target prot opt source destination Chain OUTPUT (policy ACCEPT) target prot opt source destination What I'm asking for here is advice about where to start debugging this. I can ping anything on my home lan, but nothing on the internet. Not even my IP's nameservers. And as mentioned, at the same time I'm able to ping from any of several windows boxes out to the internet. My router/fw can be set to deny specific machines outbound traffic but that is not done in this case. So the solution must reside somewhere in my gentoo install. What things should I be checking. A ping attempt like this: ping ftp.ucsb.edu PING ftp.ucsb.edu (128.111.24.43) 56(84) bytes of data. Just never moves any further, but you can see it has resolved the alpha address to numeric forum so must have contacted and received info from the nameserver. -- gentoo-user@lists.gentoo.org mailing list
