Hey guys . So i've gotten a new Netgear router (Model dgn1000) and i want to change my NAT to open... but my firmware or something is old and i cant update it
so there isn't an obvious option to change to open like there is on updated models...... Does anyone know how to get it to open?

Thanks, The maddude

1. See if your router has a Univeral Plug n Play (UPnP) setting, and enable that. If that resolves the issue, stop.

2. http://portforward.com/. Choose your router, and then choose the device/program you are trying to forward.

3. Technically, enabling DMZ is an option, just are really, really, REALLY bad one.

You cannot simple "open" NAT. When a device has the correct ports open and unfiltered then it is designated Type 2 NAT. UPnP doesn't need to be enable, but most devices prefer it enabled.

What device needs a open NAT connection?

My Xbox, my friend changed it from strict to moderate on my old router..... but now i want to change it to open if possible...

I just keep one of my Xbox's in the DMZ. The probability of someone trying to take advantage of a console is pretty slim. Though if you just want to port forward to keep the Xbox on your side of the firewall http://howto.wired.com/wiki/Set_Up_Port_Forwarding_on_Your_Xbox_360 might help.

I recommend that you don't enable DMZ. Just forward the correct ports and manually allocate the XBOX to a specific IP address of the router's DHCP. On my Linksys router is called DHCP Reservation. This will make sure that the XBOX always have the same IP address. On my network all I needed was UPnP and DHCP Reservation active and I get NAT Type 2 on both (2) XBOX 360s on the network. If was buggy until I set DHCP Reservation. I would kick me off of XBOX Live matches if both XBOXs were connected to the same match.

You shouldn't really need to forward ports, should you? Most routers have PAT rather than NAT.

It's actually PAT that makes port forwarding necessary. When people say NAT, they really mean PAT (AKA: NAPT). Whenever you have less external IPs than internal IPs, Port Forwarding may be necessary.
