Nmap and my SMC router Firewall

[Chauncey Smith]

I'm starting experiments and getting into security with my home network. I
just discovered Nmap thanks to my interest in porn and the guys in one of
the Freebsd chat rooms. I downloaded it via the ports tree and followed the
models instructions and scanned my network. It found all my wild wild west
hardware and identified the OS's on them and I discovered a new BSD Box on
my network I didn't know was there. BSDI BSD/OS 2.0 - 3.0 at 192.168.2.1
I've played with NetBSD that little brother runs on anything.. and I've got
my FreeBSD on my Intel machines....
I've never bought a BSDI's BSD/OS to install on anything . This is my
router.I discovered only after I opened Mozilla and hit the link to my
router and looked at the ip in the address field because I just knew I was
hacked and had to read those logs.

I've come to the conclusion that in every router must be a Single board
computer running some kind of OS and for stability it's got to be a BSD.
They stay up forever and receive very little if any maintaince. Well at
least mine doesn't because I can't really get to a command line and tinker.
After doing a quick web search I found out that 2.0 - 3.0 is old the newest
BSD/OS version is 5.1. So a quick we search at where I saw the model and
found a list of exploits for all OS's. Ok.. old OS most likely dated
firewall software that I really can't configure means it's time for a SBC to
act as a router. I'm starting a new project and Learning a lot more about
firewalls.

Any commitments welcome
