I am using a levelone wbr-6800 3g router and a 3g dongle. I am trying to get an open NAT with Mordern Warfare 3 on a ps3. Basically these are the results I get when pinging a server in CA.

My problem is supposed to be solved by this

I have setup my router according to that faq and I have attached screen shots.

  1. my router IP address is 192.168.0.1

  2. I have disabled dhcp and I'm hardcoding the DNS addresses. The IP address(static) assigned to the ps3 is 192.168.0.3

  3. I have placed the ps3 IP address in the dmz as shown here:

dmz

  1. I have also forwarded the ports needed by psn and mw3 as shown here in accordance to the faq.

  2. My basic setup is as shown here

Setup

With that my router should have a moderate or open NAT but it still comes up as strict.

The router also has another section for special applications but I'm not sure how to work it.

If your router has an ethernet port, I would suggest hard wiring the connection. I have the same setup, and it works, but the Ping situation is pretty much an unsolvable problem, mainly because you're using 3g.

I would suggest you get a land-line based network connection.

The problem with 3g is because for one, it allows for high quantities of data transfer by sending highly compressed, albeit infrequent, packets. Additionally, the packets travel along the following path, more or less:

PS3 > WiFi router > 3G modem > Local Cellular tower > Cellular Hub> Cellular HQ > ISP DNS > ISP Hub > and so on...

This isn't exactly accurate, but it's roughly how it works.

For Example

This is what Happens when I ping Google through my 3G modem, connected directly to my laptop.

Tracing route to www.l.google.com [74.125.71.99] over a maximum of 30 hops:

1 * * * Request timed out.

2 725 ms 419 ms 178 ms 10.159.130.73

3 143 ms 79 ms 138 ms 10.159.161.56

4 116 ms 99 ms 99 ms 10.40.128.2

5 89 ms 99 ms 99 ms 10.159.40.185

6 97 ms 99 ms 99 ms 10.159.52.150

7 127 ms 109 ms 119 ms 202.138.144.241

8 127 ms 177 ms 130 ms 202.138.145.53

9 118 ms 119 ms 148 ms 202.138.145.78

10 146 ms 119 ms 119 ms 209.85.248.62

11 137 ms 139 ms 147 ms 209.85.253.69

12 126 ms 144 ms 129 ms 216.239.48.226

13 107 ms 129 ms 125 ms hx-in-f99.1e100.net [74.125.71.99]

Trace complete.

As you can see, this is an inordinate number of hops. I suggest you try the same:

Trace route

1) Press [Windows Key] + R

2) type "cmd" (without quotation marks) and press enter

3) type "tracert [website URL]" and press enter

4) let it run through, this might take some time.

5) You should have a report like above.

If your own Trace Route settings are similar to my own, then I would advise against playing games online until you have a landline based connection.

That's pretty much the only solution I can think of, and am even in the process of getting a landline connection myself.

Hope this helps.

The number of hops isnt the problem. i just tracert to google aswell and i got 14 hops and i have a landline. The ping i have is a lot better though (around 1-5 ms) –  Serge Bekenkamp Aug 1 '12 at 12:13

I would like to add that after getting my old router replaced with a new one, I was able to get my NAT from strict to open.
