| Not sure if I should have started a new thread for this but I'll just post it here since this is the thread for the infamous NAT problem.
I've been trying to get my PS3 to NAT 2 for about a week now and I can't seem to get it. If you're in for a challenge, you're in the right place. Here's my setup. I have Windstream DSL through a Siemens Speedstream 4200 modem/router. I am then connected to a D-Link WBR 1310 wireless router and then finally to my PS3. I have disabled the wireless function on my D-Link router so everything is using a wired connection. I have also disabled DHCP on the D-Link and assigned it a static IP. There is nothing connected into the WAN port on the D-Link router. I have assigned the PS3 a static IP as well. I can connect to the internet with both my computer and my PS3 with my network in its current configuration but I get a NAT 3 connection. I have disabled the firewall within the modem and that doesn't work. I have entered the PS3s IP into the DMZ on the D-Link router and on the Speedstream modem and no luck. I've even tried entering the routers IP into the DMZ on the modem and still nothing. I think the problem is isolated in the modem. My modem shows two connections. A PPPoE connection and 2684(0) 0/35-BRG. My modem also has settings for NAT/NAPT. It is currently set on NAPT only for both connections. I can change it to enable NAT for either or both of the connections but I have to enter a static IP when I do this. If I enable it for the PPPoE connection and enter my PS3s static IP, it works. The problem is that I then lose my internet connection to the computer which doesn't make my wife very happy. If I enable NAT for the 2684(0) 0/35-BRG connection, nothing changes. I still have an internet connection and I still have NAT 3. There is an option for enabling concurrent NAT/NAPT for the PPPoE connection. I think that my answer might be there. In order to do that, it wants a public IP addres and well as a private IP address. I have the private address but I can't figure out what the public address is. I've spoken with my ISP and they gave me three IP addressess but none of them work. I'm fairly certain there has to be a way to make this work from within the modem, I just don't know what it is. I don't fully understand the advanced configuration settings of the modem. I know the problem is not with my D-Link router because even when I connect the PS3 directly to the modem, I still get NAT 3. I'm hoping there is somebody out there who has run into a similar situation that knows more than I do that can solve this annoyance for me. |
