I use an adsl router to connect to the internet. My machine is connecteed to the router via ethernet. The interface it uses is eth0. The router has a firwall on it already and it is enabled. The router also has wifi on it that is anabled and secured useing wpa encryption and password etc. I use dhcp to assign the ip address.
I installed guarddog as a firewall gui so I could enable and configure iptables. On the protocol tab I selected the things I wish to be able to connect to the internet e.e.g http, https, bit torrent, ftp etc etc. I left the ones dotn want alown. I copied exactly the same allow and disallow things to the local section of the protocal tabs so the internet and local match.
When I enable the firewall everything is blocked, I cant even get standard http access. I enable the boxes for dhcp and applied the settings again, this still did nothing. I followed a guide in Tuxmagazine for setting up the firewall but this still stopepd all network activity.
When I disable guarddog I can access my router for the internet without any problems.
Is there something I need to enable in guarddog to allow this machine access to the router?
Secondly I used firestarter a while ago when I was ona dial up connection. Is firestarter pretty secure by defsult in its standrd configuration, or does it not have any pre-set config options and that i need to configure it after the install.
Help with the guarddog problem would be appreciated
