Good day everyone! I'm currently using CFP and happy with it. IP/Port scanning from other pc's on the same subnet shows that I'm stealth. I can't use testing from sites such as GRC etc. because I'm behind s router. Yesterday, I scan again my pc from other pc using Colasoft MAC scanner, and to my surprise that other pc saw my ip and MAC. I asked on Comodo's forum if there's any way (a rule or anything) I should do to make me totally stealth to all pc's on my subnet other than the gateway and other trusted pc's, but I had learned that CFP as of v3 (not yet sure v3.5) does not support yet ARP filtering. Sorry for the long intro , I just want recommendation for any good/free firewall that can handle ARP filtering. I've read about CHX-I but never tried it yet because i believe it's no longer being develop. I'm using WIPFW now (with CFP) but I don't see any ARP filtering rule. Thank you very much in advance for any suggestion. More power!
