While reading up on various tips'n'rules for IPChains, there are some warnings about when(at bootup) and how(the rules) to implement a firewall. So just how insecure is your average Linux machine after a fresh install? If all you have done is setup a PPP connection, are you greatly at rist? I'm just assuming there may be a lot of risk as even a newbie IPChains firewall seems to be low-security. BTW: I visited a site that generates a firewall for you. Didn't understand a word of it :-)
