Postby Daemon Wolfe on Sun Jun 14, 2009 3:01 am

greetings, i am a utter newb, i love the look and feel of mint for one, but i am confussed on something, which is do i need to run firestarter? if so if i read a previous post's on this right, you run the wizard once and then you do not need to constantly run it everytime on boot...but that reminds me on something esle, do i need to run firestorm? do i need to worry about a firewall period? i am rather confussed and have tried to figure this out for the past week...

you basically don't need a firewall if linux is your only system. And even if you did want to run one, I'd recommend something like Uncomplicated FireWall (UFW)

i am going to check out the UCW right now, and thank you so much for the answer, after i posted here, i did alot more research, and bounced a few idea off a friend, if i got it right basically Mint does the firewall options for you, once it is installed, as a background operation....but thank you for the advice :D

Daemon Wolfe,

Take a peak at the thread below. It may be somewhat enlightening. :-)

If your connected to a router you may already be behind a "hardware firewall" anyway ;

From http://www.grc.com/nat/nat.htm :
A NAT Router's Inherent Security
Although NAT routers are not generally purchased for their security benefits, all NAT routers inherently function as very effective hardware firewalls (with a few caveats examined below). As a hardware firewall they prevent "unsolicited", unexpected, unwanted, and potentially annoying or dangerous traffic from the public Internet from passing through the router and entering the user's private LAN network.

The reason they do this is very simple: With multiple "internal" computers on the LAN behind the router, the router must know which internal computer should receive each incoming packet of data. Since ALL incoming packets of data have the same IP address (the single IP address of the router), the only way the router knows which computer should receive the incoming packet is if one of the internal computers on the private LAN FIRST sent data packets out to the source of the returning packets.


I don't rely on this in Windows however. In Windows I install a firewall not to protect it from bad people calling in but to prevent it from "calling home" :wink:
