Hi,

I can't seem to get NAT Type Open in MW3. uPnP is enabled and uPnP status says that that UDP3074 is forwarded to my computer, but no go:

Code:

3074 keep state udp (this PC's IP) DemonwarePortMapping

I've pretty much isolated the issue to the firewall, or at least some MW3->firewall combo, since I tested with a Cisco/LinkSys modem/router (also tried with just the router part connected to my regular modem) and then I got NAT Type Open. Cisco/linksys logs say:

Code:

Mon, 2011-11-28 20:10:25 - Returning UPnPError 714: NoSuchEntryInArray
Mon, 2011-11-28 20:10:25 - AddPortMapping: external NULL:3074 to (this PC's IP):3074 protocol UDP for: DemonwarePortMapping with timeout:0
Mon, 2011-11-28 20:10:25 - no permission rule matched : accept by default (n_perms=0)
Mon, 2011-11-28 20:10:25 - redirecting port 3074 to (this PC's IP):3074 protocol UDP for: DemonwarePortMapping
Mon, 2011-11-28 20:10:25 - creating pass rule to (this PC's IP):3074 protocol UDP for: DemonwarePortMapping

The strange bit is that MW2 works, along with "everything else" that uses uPnP.

Please help me out here, I'm running out of hope...

Thanks,
Floddy

I am having the same issues. I even setup a NAT rule for the required ports to my PC (as per a post on the IW forums) and still had strict NAT. However MW3 isn't the only issue, Tom Clancy's HAWX gives me the same issues and I haven't been able to pinpoint that, however all my other uPNP games work just fine.

OH HAPPY DAY! 

Thank you SO much, NAT type is now "open"!

However, instead of doing as described in the docs, I added a new rule which applies to the specific port that MW3 uses.

hmm can somebody help me out?

i have configured 3 rules

tcp/udp on port 3074
tcp on port 27014 to 27050
udp on port 27014 to 27030

and activatet stati-port on NAT-Outbound in the mapping with the description "Auto created rule for LAN to WAN "

are these steps correct???
still geting Nat-Type > middle

beta,

I saw the same thing too.  I had strict NAT, did the suggested change to make it static, that took me to moderate.  I did a reboot via web gui, still stuck at moderate.  I did a halt, and then cold reboot of pfsense, and that took it from moderate to open.  Apparently a reboot (via gui) doesn't do the same thing as a halt/ cold restart?

Anyways, it's working, and I'm happy...
