Did that Jsamp still get NAT type 2. Any other ideas i tried all these youtube turtorials and still nothing.

I have had type 2 the whole time.

Basically what DMZ does is put you outside of your routers firewall and allow all connections. It could help. Have you tried it?

ok. Just so you know to display images go like this

lol nvmd you fixed it

I do not use NAT, there is no real reason too unless someone specifically targets you (you make someone mad, you are target of a federal investigation....), and, you have a DMZ set.  If you have no DMZ, there is no neet for NAT...  The NAT still won't hide the address of your CABLE MODEM, or DSL MODEM, just the IP address of your PC on the LAN.

I guess I am going to have to fully explain this thing: The main reason for NAT, is that router appears to the Internet as a single machine with a single IP address (but your MODEM already has SINGLE IP ADDRESS). This effectively masks the fact that many computers on the LAN side of the router may be simultaneously sharing that single IP. This is good for the Internet since it helps to conserve the Net's limited IP space.   You should only use NAT if you are using a PC and ICS.  The ROUTER can be set to ignore pings, and all kinds of THINGS, so no need for NAT, unless you have other people on your LAN that you don't want your IP address seen. 

Well, your ISP MODEM used, has an IP address, ONE, that's all they see anyway.  The router assigns an IP address to the PCs on the LAN side, so, they don't see the 192.168.1.XXX, they see your cable modem's IP address, NAT or not, if they want you, they'll get you.  The MAC address of the LAN hardware in the PC is what is used in the routing table, IN the router to assign that IP address to with or without NAT.  So, NAT is kind of a redundancy in some ways, especially of you do not have the DMZ set, and, there is no reason to unless you have a WEB or FTP server you want running, which ISPs do not like.   I have been running no NAT, and no DMZ for years, and I have never EVER had problems.

OK, SO, There is a lot of OVERHEAD for NAT: Since the NAT enabled router links the internal private network to the Internet, it sees everything sent out to the Internet by the computers on the LAN side. It memorizes each outgoing packet's destination IP, and port number in an internal connections table and then assigns the packet its own IP address; and, one of its own ports for accepting the return traffic (here lies some problems).  Lots of work!  Finally, it records this information, along with the IP address of the internal machine on the LAN, that sent the outgoing packet, in a "current connections" table.

When any incoming packets arrive at the router from the Internet, the router scans its "current connections" table, to see whether this data is expected by looking for the remote IP and port number it came in on, in the current connections table. If a match is found, the table entry also tells the router which computer my MAC address, on the private LAN is expecting to receive this incoming traffic from that remote IP address. So, the router then re-addresses (translates) the packet to that internal machine and sends it into the LAN.

See, this is where the PORTS issue can be a problem, since the PORT being used may not be compatible with the port needed for GAMING, and REMOTE ACCESS for PCs, and what not. SO, then you need Port Forwarding enabled, to configure routers to forward unsolicited packets arriving at specified router ports to specified machines within the router's LAN network. This can be useful when using some instant messaging, VoIP, or peer-to-peer systems that are otherwise unable to penetrate the firewall that NAT routers inherently create.  A Routing DMZ machine can also be specified, separately or additionally, to receive any and all unsolicited traffic that is not otherwise being returned to other machines on the router's LAN network. This puts the specified machine "out on the front line" of the Internet to receive anything that might be aimed at the router's public IP.

SO, here you have the simplicity of not using NAT while gaming, there is no reason to use NAT while your are on M$ Live or Sony's version.  This is mainly used for people who just can't get off their PCs, and surf the internet ALL DAY, and NIGHT, and download crap upon crap, and visit PORN thumbnail sites that ALWAYS have undesirable data coming in.  So, you should have protection on YOUR PC side, because lets face it, the PS3 doesn't need it for ON-LINE GAMING.   IF you use the PS3s web browser, like a PC, then maybe, but I don't, and never will, umm, I got a PC for that. 

So, the quick answer is, for ON-LINE GAMING with a console, you DO NOT NEED NAT!

You either need PAT or NAT to transmit data outside of you LAN (assuming multiple hosts) and to the Internet. If you don't use NAT you have to use Port Address Translation. To get a MAC address (layer 2) you have to use some sort of PAT or NAT to get it to layer 3 (IP) to get through the rest of the 7 layers of the OSI model. If you don't use NAT or PAT every PC on the internal network would have to have a public routable IP address.

Perhaps i am misunderstanding what you are trying to say.

blimpie is it possible to connect your PS3 directly up to your cable modem when you play? That way you wouldn't be behind NAT at all.

nat type 2 or 3... switches time to time

nat type 3, which sucks looking to get a new router which supports dmz settings so i myte get nat type 2.

yea my house is wired like crap. basically one router from the garage has like 6 routers connected to it which spread through all my Ethernet direct wall connectors. all wired routers one wireless.

what the hell.  Maybe you should just buy one of those routers they use like for businesses and schools where they can handle like 20 wires.
