Linksys e1200

Hello....I was wondering if anyone can give me a quick how-to on changing my nat type from 3 to 2. If you need any information, I will be happy to provide. I am kinda ignorant on this stuff.

You will likely get better results by posting at:

Also be aware there is no formal technical definition of NAT types 1 to 3.

I'm guessing this is connectivity for XBOX LIVE, PSN or something similar?

Yeah....sorry about that. Cisco was also on my modem. Wasnt entirely sure if this was the right place or not.

Also, yeah, it is for PSN connectivity.

Guessing this is where you got the NAT Types list from here, right? Again, they have no basis in how NAT
works or connects in real life. So off the top of my head, your options are DMZ mode for the PS console,
uPNP (MAJOR security risk, IMO), or figuring out which TCP and UDP port(s) you need to forward on either
the modem or home router to get this to work.

Slightly off topic, you have a Cisco modem (guessing it's a DPC 38-something?). Is it in bridge mode with
the Linksys e1200? IE if you log into the Linksys's admin pages, the Linksys is getting a non-10.x.x.x,
172.16.x.x or 192.168.x.x IP address on it's WAN interface?

UPnP is risky if you send it out your WAN port but why would you?
To see if you are exposed run the UPnP scan here:
»www.rapid7.com/resources/free-se···2013.jsp

That site is linked to from here:

For me, I think they may be slightly over playing the vulnerability BUT, I am not a security expert so I am prepared to have my mind changed.
