I've a cablemodem Thomson vcm 770. The isp, gived it to my like a cablemodem, so i can get 3 different public IP's for my machines, but that is the maximun.
I'm wondering if this is real secure or not, because the cablemodem is in transparent mode, so i think nobody can attack it from internet... but the question is... is that really? Anybody could make a Mitm? Am i secure? Can the machine which is connected be attacked?
Thx for all friends... Im just a newbie here!
