Hello this is a NMAP of my little blue linksys/cisco router , I have a DMZ'd server being pushed out from the internal , this is what i got when I NMAP the 192.168.1.1 from the inside

[root@honeypot ~]# nmap 192.168.1.1

Starting Nmap 4.11 ( http://www.insecure.org/nmap/ ) at 2008-04-02 04:39 CDT
Interesting ports on 192.168.1.1:
Not shown: 1666 closed ports

4224/tcp filtered xtell
4480/tcp filtered proxy-plus
MAC Address: 00:00:00:00:00:00 (Cisco-Linksys)
I changes my MAC Address for security purposes

Any clue if this is a normal nmap with my current config ????
From What I remember of my last nmaps it wasnt like this

I Flashed the Firmware of " said router" and the NMAP went back to just port 80 HTTP , I was curious if someone got a hold of my router for nefarious purposes , But I guess Ill never know

you have so much ports open that any hacker could brake into your pc =] if your using windows download shadow security scanner it shows you your vulnerabilities and tells you what to download to fix them
