Since I've installed Firestarter I have encountered connectivity issues that are all resolved by disabling the firewall. I'd prefer to have the firewall running and allow all the traffic I normally use:
- Wired network + wireless network, whichever I'm connected to, or both (1)
- OpenVPN
- VirtualBox internal network
- Samba (for accessing shared Windows folders and sharing folders to Windows) (2)
- BitTorrent
- And everything else I use that I can't think of :)
All the above works without a firewall. I thought Linux was super secure (I update regularly). Do I really need it?
(1) I used the Firestarter wizard and selected wlan0 as my primary connection, now whenever I plug in a network cable, I lose all connectivity. Should I just redo the wizard for eth0, or will I then lose wlan0?
(2) If it makes a difference I'm sharing a directory that I share between local users using bindfs. See my answer to Good and easy way to share files on local machine
