PS3 NAT issues

[KingBroly]

I'm having major NAT issues with my PS3 right now. Let me explain thoroughly so CAG's might be able to help with the situation. First off, I've spent 2 days on the phone with people trying to figure out what's going on, and no one can figure this shit out. Not my ISP, not my router manufacturer, not Sony.

Okay, so as of 2 days, my PS3 had a good wireless connection and I could connect with other people and talk to them over PSN. I have Firmware 2.43, so that might help. Anyway, we've had major connection issues since then and about 5 technicians are in the area trying to fix the internet (it constantly goes up and down all down). Anyway, after a lot of trial and error, we got the router back up (after a firmware upgrade) and the PS3 comes back with NAT3. Now here's where it gets tricky.

We get a new router, that also gives me NAT3 for the PS3, with UPnP unavailable to boot. 360 is still Open NAT, Wii...is there. The only problem I'm having is with the PS3. Here's something weird. I decided to hook my PS3 directly into the DSL modem, and instead of giving me a NAT1 or NAT2, it comes up with NAT3. So, for the past day I've been forwarding ports on the modem to no avail.

So, I ask. What the hell is wrong here? Is my PS3 busted due to firmware 2.43 (The non-engrish one)? Is my ISP's modem borked? Are the technicians screwing with everything? Have these 2 routers infected their NAT ways onto my modem? I don't know what the hell to think anymore.

Who is your isp and what router are you using?

[KingBroly]

My ISP is Bellsouth, and I was using a Linksys WRT54G. As for modems, it's a Motorola 2210.

[Malik112099]

the motorola 2210 has router functions along with being a modem..your problem is that you are behind 2 routers/firewalls .. (i had this same exact problem with embarq) you need to set up the 2210 by enabling UPnP. You need to connect the linksys as a wireless access point (do a google search..there are a lot of topics about it)..you will basically let the motorola do the router functions and the linksys will become just a dumb access point...

[KingBroly]

How do I enable UPnP with the Motorola? I don't see anything that will allow it.

[Malik112099]

you have to log into it...

try 192.168.2.1 or 192.168.1.1

[KingBroly]

I have logged into it (it's a DSL modem provided by my ISP, so it's 192.168.1.254) and there is no option for UPnP anywhere.

well dont worry about that...the main concern is setting up the linksys like a wireless access point and turning off its router functions

log into the linksys and turn off DHCP then take the cable going from the motorola to the linksys and plug it into port 1, 2, 3 or 4 on the linksys (you do NOT use the internet port anymore when using the linksys as an access point) also..the internet light on the front of the wrt54g probably will not light up anymore

now turn off then on ANYTHING that needs to access the wireless because it will have just lost its IP address...once you turn it off then on (in my case I only needed to restart my pc since it was the only thing on at the time) it will get a new IP from the DHCP server on the motorola...

now when your PS3 connects it *should* be a NAT Type 2 and you'll be good to go

What's so bad about DHCP exactly and what should I change it to?

DHCP is Dynamic Host Configuration Protocol

http://en.wikipedia.org/wiki/Dhcp

It basically assigns IP addresses automatically to devices trying to use the network. Without it you would have to manually assign IP addresses before using the network.

It is bad to be behind 2 routers because they are usually firewalled. When you have 2 routers on a network trying to perform router functions it interferes with free communications (or whatever you want to call it) between the devices and the internet. By turning off DHCP on one of them and making it a "dumb" access point you are taking one firewall/DHCP server out of the equation and making it easier for those communications to occur.

You might be thinking "why is my nat on the 360 open but the ps3 is type 3 (strict)? well that is because the xbox 360 only checks what it is immediatly connected to the internet through (linksys) and doesn't check through to the motorola.....the PS3 does check though

[KingBroly]

Okay, let me ask this. When I plug my PS3 into my modem, it should give me a NAT 1, right? Then why if I plug my PS3 into my modem (not through a router), it shows up as NAT 3?

Okay, let me ask this. When I plug my PS3 into my modem, it should give me a NAT 1, right? Then why if I plug my PS3 into my modem (not through a router), it shows up as NAT 3?

because the PS3 uses different ports for communications...if you don't have UPnP (universal plug and play) enabled then the modem is not letting those ports freely communicate.....you either need to allow UPnP or set up port forwarding for all of the ports that the PS3 uses

[KingBroly]

But if I setup my PS3 wirelessly through my router, UPnP is enabled (but is not an optionn in the modem). And forwarding ports still does nothing to resolve the issue, even through both. I'm beginning to think that the technicians in the area are the ones causing this because they've been in the area the last few days because the network's been going up and down, and because of the work on the line.

[Malik112099]

if you want to use the linksys as a router then you need to bridge the modem....no matter what you do if you just connect the modem and the router without configuring them you will have nat problems

[KingBroly]

Well, I opened ports for the PS3 on my modem AND my router and still nothing. It's setup on DCHP, and for some reason, if it's changed, the whole damn thing dies.

yeah....you NEED to setup the linksys as a wireless access point (turn DHCP off and plug the ethernet cable coming from the modem into port 1, 2, 3 or 4 of the linksys) then everything needs to be turned off and back on so the ip's are released and new ones can be assigned

[shrike4242]

Putting the router as an AP is the wrong way to do this.

You should put the modem into bridge mode, which stops it from doing any routing. It turns the 2210 into a "dumb" DSL modem, which just goes out and talks to the ISP's network. The router tells the modem on what to do.

In any case, the routing capabilities of the modem pale to the Linksys router. Using it to do your routing is a very bad idea.

Put the modem into bridge mode by following these directions:
http://answers.yahoo.com/question/index?qid=20080802124531AAwfL3U

Info about the 2210:
http://www.dslreports.com/faq/amfaq/2.6.1_Motorola_2210

Put the 2210 into bridge mode, reset the Linksys router back to normal, and open up all your ports for your PS3.

Now that I look over the pic of the 2210, I have that same modem for my AT&T DSL and I've never had any issues with my PS3 not getting a Type 2 NAT. I'm using a WRT54G as my router, though I'm running DD-WRT on it, and it blows the doors off the standard Linksys firmware. I have a 360 running with an open NAT, a PS3 running with a Type 2 NAT and a Wii set up with a static IP address via DHCP reservation. All of them work without any issue, and all at the same time doing downloads.

I highly recommend setting up the PS3 and the 360 with static IP's, once you get everything sorted out. Makes everything so much easier.

[Malik112099]

I have Embarq DSL with the modem (EQ-660R) doing the routing (DHCP enabled and UPnP on) while my wrt54g v.6 (normal firmware) is a dumb access point...my PS3 is a NAT type 2 and my 360 has an open NAT and have a LOT of things accessing the internet wirelessly without any problems (2 xbox 360s, ps3, ds lite, psp, ipod touch, MS zune and my pc)

the routing capabilities mean nothing in this case as long as DHCP works fine and you can enable UPnP or do port forwarding.

either setup will work, but the main thing is to NOT have both trying to perform routing capabilities at the same time

also...static IPs arent neccessary if you have UPnP enabled...if you can't enable/use UPnP for some reason then you need to assign static IPs and do port forwarding for them)

[KingBroly]

I'll give what you said a shot in the morning, Shrike. I just found out that on Monday, they had my dad do a firmware update (to 1.02.5) on the Linksys router (nice of him to tell me that NOW), so that might be some of the cause right there.

I've already opened up ports for the PS3 on both the Linksys and Motorola, and nothing's changed. My modem's setup for PPPoE, while the Linksys is on DHCP (which, if I change, kills the network for some reason). Also, Linksys is on 192.168.2.1 while the Motorola's on 192.168.1.254 if that means anything.

Also, I was given a static ip address for the PS3 and it never connected.

EDIT: Also found out how to enable UPnP on the modem. No changes besides enabling it.

if you disable DHCP on the router you HAVE TO HAVE TO HAVE TO disconnect the cat 5 cable from the "internet" port and plug it into one of the numbered ports..you HAVE TO do this if you turn off DHCP

[KingBroly]

Well, let me clarify what I mean by it dies. It never goes to the Settings Changes are Successful screen, but instead just sorta sits around for a couple of minutes doing nothing, then I can't connect. But if I unplug it, everything goes back to the way it was.

hold the reset button down for 30 seconds then adjust your settings

also...static IPs arent neccessary if you have UPnP enabled...if you can't enable/use UPnP for some reason then you need to assign static IPs and do port forwarding for them)Glad it's working for you that way, though I'd never use a DSL modem as my primary router.

UPnP causes more problems that it fixes, which is why I turn it off and do port forwarding. Especially with devices that don't work well with UPnP, plus it puts overhead on the router over port forwarding.

To the OP, I suggest you factory reset the router, factory reset the DSL modem, put the modem in bridge mode, and start over from scratch with the Linksys router doing the routing. Plus, I'd make sure it has the most recent firmware on it before doing the factory reset.

[KingBroly]

Every time I try to switch the configuration on either, they crash. I think they (ISP) must've changed some security thing or something, because it shouldn't crash like that.

For the Linksys router, it has the most recent firmware, and before getting it last week, it was showing me NAT 2.

[KingBroly]

Okay, can't change the settings yet. The Network guy should come this week though.

BUT...I still have NAT 3, BUT...I can talk/hear people with a mic so...yeah?
