I have recently had an issue with Firestarter preventing Firefox accessing the Internet. I have used Firestarter in the past with Hardy Heron and recently switched to Precise Pangolin.
The policy settings I used with Hardy for Firestarter are:
outbound traffic policy
restrictive by default - whitelist traffic
HTTP 80 - everyone
HTTPS 443 - everyone
POP3 110 - everyone
SMTP 25 - everyone
these settings worked fine on Hardy and until this past Friday worked fine on Precise. Then I started to get the message Server not found when opening Firefox. The only way to access the Internet is to disable the firewall. In case it's a hardware issue, I am using a Zepto Znote 3215W laptop (wired Internet connection).
Am I doing wrong somewhere?
Any help greatly appreciated (I'm still learning about Linux).
