Issues Addressed:
• Resolved several issues with parties getting disbanded unexpectedly.
• Additional measures to prevent the “Transmission error” and other disconnects. This was most likely to occur with large parties where party members had mixed NAT types.
• Updated handling for UPnP-enabled routers to improve matchmaking conditions where users had strict or moderate NAT types. Also added in-game communications so that all players are aware of their NAT type in the Player Match party lobby.
• Addressed an issue with VOIP icons not appearing when USB headsets were plugged in prior to game launch.
• Prevention of exploit that allowed players to keep custom classes and killstreaks after prestige.
• Addressed an issue where Flak Jacket Pro would not always protect against ground fires left by Napalm Strikes.
• Prevention of users losing their killstreak reward when switching classes at the start of a new round in round-based game modes.
• Addressed an issue where the incorrect perks would appear when spectating another player under certain circumstances.
• Added round start explosive delay to China Lake grenade launcher to give it the same round start limitations as other explosives.
• Contracts will now reset when the player Prestiges.
• Prevention of Valkyrie rocket exploding upon release under rare conditions.
• Prevention of Gunship and Chopper Gunner failing to give player full control under rare conditions.
• Prevention of an issue where a player will get teleported outside the map boundaries under very specific circumstances.
• Additional security measures to enhance detection and banning capabilities.

Gameplay Tuning:
• Limit the ability to re-roll supply drops using Hardline Pro to Care Packages only, no other killstreak drops.
• Added a negative influencer to all spawn points to decrease the chances of spawning near an enemy. This will further improve spawning protection on top of previous updates.
• Additional sound mix tuning for Ninja Pro users – increased ranges and volume of enemy footsteps, and removed player footstep sounds on concrete material types.
• Increased headshot multipliers for sniper rifles. Sniper rifles with suppressors equipped will now always be ensured one-shot kill headshots.
• Subtle increase in sniper rifle accuracy when scoping in.
• Added a render delay to the red diamond player indicators that appear when controlling the Gunship, Valkyrie Rocket and Chopper Gunner. When a player first spawns, this will not appear for a period of time.
• Additional minor reductions in knife lunge.

PUTTING YOUR PS3 IN A DMZ

Firstly you may be wondering what a DMZ is, this stands for a demilitarized zone. it really means that rather than opening just one port on your routers firewall you are actually opening every single one. Port opening is another simple process, however it takes a bit of time to find exactly what ports need opening, and sometimes, the ports listed may not solve the problem you have.
There is no risk regarding security/virus' etc when using this with the ps3, Your router will only send the traffic through to the DMZ that you have specified.

Putting your PS3 into a DMZ is not a bad thing, and is much easier than opening port for the reason listed above.

Now you may need to do this for some of the following reasons:

* Not being able to join rooms
* Not being able to speak over headset
* Not being able to hear over headset
* Not being able to join games which are hosted by certain people
* Any problems to do with connectivity to the PSN or game specific servers, especially if your computer will connect to the internet, but PS3 won't.
* Problems with media servers

Now on with the guide.

The Guide!

To put your PS3 into a DMZ (To be done on the PS3 Console)

Firstly, you will need to assign your PS3 a static internal Ip address. This means that everytime your PS3 connects or "talks" to your router, the router will assign it a different internal IP address. These IP addresses typically run in series. So for example, if your PS3 is the second device communicating with your router, then it will be assigned an ip address of 192.168.1.3. However, if you choose to use your PS3 without the computer being on, the assigned IP address your PS3 has will be 192.168.1.2. As this is different, and obviously will change, it would be stupid setting a DMZ up on one of the above Ip addresses, unless your PS3 was the only device that would ALWAYS connect using that specific IP.

To make sure that your PS3 is always assigned the same internal IP address by your router, you will need to go to the "Settings > Network Settings > Internet Connection Settings" option on the PS3 Cross bar menus.

You will be presented with an option which primarily asks whether you are using a Wired or Wireless connection. Obviously, you will choose the option which refers to you. If choosing the Wireless option you will need to input the security details in use on your router *If you are not currently using wireless security, i strongly reccommend you do so ASAP*

Both selections should show a page called "Address Settings". Here you will need to select "Custom". Another page will then display entitled "IP Address Setting". The option "Manual" will need to be selected.

This will display a page where customisable IP Addresses are available to be selected.

IP Address - This will need to have the Static IP address in it. Personally, i use 192.168.1.101. I use this because it is extremely unlikely my Router will ever automatically assign this IP Address to a device, as i will never have 100 other devices connected to the same system.

Subnet Mask - Is always set to 255.255.255.0

Default Router - Is the internal IP Address of your router.
To get the exact ip of your router you should go to
Start
Run
cmd [Hit Enter]
Type in ipconfig and hit enter, this should come up with all the ip addresses to do with your computer and the network. The address you will need to enter in this option is listed as "Default Gateway". There might be a few different networks depending on your computer specifications but your looking for the Ethernet adapter.

Primary DNS - Same IP Address as "Default Router"

Secondary DNS - Same IP Address as "Default Router"

After entering all of these IP Addresses, you will now click "Enter" or hit the "right" button on the D-Pad. This will take you to a screen which says "MTU" at the top.
If your router has the option to change the MTU size then use 1500 in bytes, this is to be done on both the PS3 and the router page.
If you cant change the MTU size then set this to automatic

The next steps are very simple. You do not want to use a proxy server unless you connect to the internet using one, however i can be of no help there, and you should enable UPnP if your router supports it. If you get errors when you test the connection later on, then turn this off and try again.

To put your PS3 into a DMZ (To be done on the PC)

Now head over to your PC, and load up your internet browser. In the Address Bar, (The place where you put WWW.) type the IP Address of your router (the one you found using the Command Prompt earlier under "default gateway")

This will take you to your Router Configuration Page.
There may be a security login page or popup. if you don't know the Username and password then Google your router for the default login, check on your router label or ring your ISP.

Every router interface differs from an other, and depending on what router firmware update you last installed, router interfaces can differ, even on the same model routers. This means that you will need to search the router config page yourself. You are looking for any mention of "DMZ" or "DMZ Host"

When you have found this, it will ask you generally to input the IP Address of your DMZ Host, which is just the static IP address you assigned to your PS3 earlier, my example was 192.168.1.101, so we'll stick with that. Then click "apply" or similar.

You should then turn off everything running on your home network. PS3, PC, Router etc. This is solely to make sure that the changes are applied as soon as possible.

This should fix all of the problems as listed earlier in this guide, and probably some other issues.

If you do need any help then when you post, along your with problem could your also give some more details. Like:
- Your Connection, ADSL or Cable.
- How you have your network setup.
- Your router Make and Model.
