Linksys WRT54G v5 not forwarding ports to wireless?

I think that the subject line describes the problem fairly well

I have a speedstream 4200 dsl modem that forwards all it's traffic to
the linksys wrt54g and then forwarding specific ports from the router
to the 4 wired PC's in my home network works just fine. However, it is
a different story for my wireless laptop and pc. All machines
including the wireless ones have static ip's. They can communicate
with each other fine from within the lan, but I can't get any outside
request to hit a wireless device for game servers, filesharing, etc. I
thought the port range forwarding in the linksys worked for both wired
and wireless. Isn't it supposed to? Anyone run into this problem or
know how to deal with it?

I don't. I have my news reader set to not display all the header
garbage including the subject. Is it that difficult to write the
problem you're trying to solve in the subject?

Incidentally, thanks for including the version number of your WRT54G.
The latest firmware is 1.00.9 for v5. Is that what you're using? If
not, update.

How do you have the SpeedStream 4200 setup?
Are you using the DSL modem to login to the ISP with NAT enabled in
the 4200? Or do you have it set to "bridged" mode, where the 4200 is
just a modem, and no NAT? See:
http://forums.ricknmiasworld.net/5100b/ppplocation.htm
(This is for the 5100 but the 4200 is similar). Which way do you have
it set?

Hint: If you check the WAN settings on your WRT54Gv5, and they say
192.168.1.xxx for the IP address on the WAN side, then you have your
4200 setup for "PPP is in modem" mode.

Clue: If you have it set for "PPP is in modem", then you have to port
forward the modem's NAT as well as the WRT54G v5. Change it to
"Bridged mode". There's some notes on DSLreports.com on how to do it.

162.40.48.58 PTR record: h58.48.40.162.ip.alltel.net
Looks like you're on Alltel.net. I'm not sure how they setup their
DSL. Digging....
| http://www.alltel.net/alltel/portal/...rkinstall.html
Yep. Alltel uses PPPoE. They want you to install the login and
password in the modem. Bad idea because there's no port forwarding
for the NAT in the modem. Setup the modem for bridging, move the
login to the WRT54Gv5, and do the port forwarding in the router.

Yes, I upgraded the firmware to 1.00.9. Apparently earlier versions
had some serious UPnP issues, but i'm still not convinced that works
well in the latest.

Earlier I had attempted to do exactly as you say and set the modem up
as a bridge only. However, the option literally is not there. I'm not
sure if it something Alltel has screwed with to remove it from the web
config. MAYBE if I reset to factory settings and then don't use
Alltel's install CD, I could get that to work. If that turns out to be
possible, will this even fix the problem of wireless not being
forwarded any ports while wired is?

I didn't want my bad attitude to get in the way of this
troubleshooting exercise, but I don't deal with too many WRT54Gv5
routers. The reason is that I've wasted large amounts of time dealing
with these dogs. When I see one, I give the customer the choice of a
similar replacement at cost, or another exercise in troubleshooting
firmware bugs at $75/hr. They always take the new router.

>Earlier I had attempted to do exactly as you say and set the modem up

Can you kindly confirm that the modem is doing the PPPoE login and has
functioning NAT as I asked in the previous message? If the WAN port
IP address on the WRT54G status page shows 192.168.xxx.xxx, then it's
in this mode.

Another fun test is to try it without the router. Just plug the PC
into the modem directly. Then check your IP address on the PC with:
Start -> run -> cmd <enter>
ipconfig
If it shows 192.168.xxx.xxx, then you're in the "modem does PPP" mode.
However, if it's a routeable IP address from Alltel, then the modem is
in gateway mode.

Dunno. It appears that Alltel has disabled the bridge only mode in
the 5200:
http://www.dslreports.com/faq/10925
No clue on the 4200. You may need to ask in the Alltel forums for
advice on what others are doing with similar issues. With the low
cost of used DMT DSL modems, you might consider just buying another on
eBay.

Lots of hits from a Google search of "Speedstream 4200 bridge".

>MAYBE if I reset to factory settings and then don't use

I'm not familiar with Alltel's setup CD. We have PBI/SBC/AT&T DSL on
the left coast. Similar setup but may not be identical. What I do
when faced with the identical problem:
1. Connect the PC directly to the modem.
2. Have the modem deliver an IP address with it's built in DHCP
server.
3. Go the the PPP setup page in the diagnostics.
http://forums.ricknmiasworld.net/5100b/ppplocation.htm
4. Important: Write down the IP address of the DSL modem on a
post-it note and tape it to the bottom of the modem. You may need
this as there is no hardware reset button (saves 10 cents).
5. Set the modem to bridging mode. Ignore the warnings of impending
doom.
6. Put the wireless router back into the system. Setup the PPPoE
login and password in the router. You should be back on and port
forwarding will now work.

>If that turns out to be

If you have to ask that question, you apparently don't understand how
this works. With *BOTH* the modem and router doing NAT translation,
you would need to configure *BOTH* the modem and router to do port
forwarding. That's easy with the WRT54G, but there's no such port
forwarding feature in the modem. By disabling the useless NAT feature
in the modem, you end up with only one box that needs to be port
forwarded, which should work. Got it now?

Oops, I meant to make this more clear in the last post when I said
there was no option for bridged mode. The dsl modem is indeed doing
the PPPoE login. It indicates so in the managment interface (though
there is no way to change this, or disable it). The IP address that
the WRT54G router reports for itself is 192.168.254.1

Also, under the NAT/NAPT setup section NAPT only is selected. The
other choices are disabled, NAT only, or NAT and NAPT concurrent.

Looking at screen shots from the manual PDF, I notice a Bridge Mode
menu item which is supposed to be there but is not present on my modem.
Silly Alltel. I feel I am being charitable with that adjective.

Fortunately, there is a hardware reset button on this model. I can
forsee myself really screwing this up... in fact I already did once and
made good use of the button.

Here is where I can proceed no further, since there is no option for
bridging mode. This is also where I ended up screwing things up as
mentioned above. I tried to force it into bridging mode by simply by
disabling stuff. I say "stuff" because I have slept 3 times since
then, sorry. The end result was that I lost access to the management
interface but it wasn't working correctly as a bridge. Handy reset
button.

It's possible that I am messed up in my thinking about this since I am
somewhat new to networking. I understand the redudancy is not needed
and in a proper setup the NAT feature should not be used on the modem.
However, it seems like it should work, because there is indeed a port
forwarding feature on the speedstream. (Yes, port forwarding to the
only device that is connected to it seems dumb). For example, on the
modem i forward port 7778 (used for unreal tournament) to
192.168.254.1. Then on the WRT54G I forward port 7778 to
192.168.1.100, which is my wired pc. I can host unreal tournament
games perfectly. If I change that port forwarding rule on the router
to forward port 7778 to 192.168.1.104, which is a wireless pc, then
nobody can connect to the game server.

I wish I had known the WRT54Gv5's reputation before buying it. I just
got what BestBuy had. I still have the receipt, so if this looks like
a firmware issue, then maybe it would be worth the 45 minute commute to
trade it.

Thanks so much for the help you are providing me, and many others in
this group!

OK. Then then modem is doing NAT.

I have no idea what NAPT means. However, if since you have a reset
button, there's no harm in disabling NAT. It might do the same thing
as bridged mode. Dunno, but seems likely. If you do that, be sure to
remember to setup the WRT54Gv5 to PPPoE with your login and password.
If it fails to work, reset the modem, and put the wRT54Gv5 back to
DHCP.

Grrrr....

Ah, my kind of user. I'm a believer in "Learn By Destroying". If you
haven't messed up the settings, you don't understand what they do.
Nicely done. Keep going...

Not a problem. Even the "experts" screwup.

>I understand the redudancy is not needed
>and in a proper setup the NAT feature should not be used on the modem.


What you currently have is called "double NAT". It's not for
redundancy, reliability, or anything useful. It's just a side effect
of having two boxes that are both doing NAT. You only need one to do
NAT in this case.

Well, if you wanna do it that way, you can disable the 2nd NAT in the
WRT54G easily enough. This is going to involve LOTS of changes. Also,
I wouldn't do it this way. I would buy a DMT DSL modem that acts like
a bridge, not a router.

- Setup the port forwarding in the Speedstream 4200 with port
forwarding.
- Assign a static IP address to the WRT54G internet (WAN) port that's
compatible with the SpeedStreams IP block. 192.168.254.100 should
work. Netmask = 255.255.255.0. Gateway is the Speedstream at
192.168.254.254. Use the real DNS server IP's.
- Disable the DHCP server in the WRT54G.
- Connect a CAT5 cable between the Speedstream 4200 and one of the
*LAN* ports on the WRT54G. Do NOT plug anything into the WAN port.
Make sure the lights come on when you plug in this cable or you may
need a cross over ethernet cable.

That's it. The DSL modem does the PPPoE login. The WRT54G is now
just a wireless access point and not a wireless router. No NAT in the
WRT54G. DHCP from the Speedstream should assign an IP address to the
computer of 192.168.254.xxx.

What a waste of horsepower.

yeah, I know. I have the bad habit of researching my purchases AFTER
I make them. Sorry.

RFC 2663 "IP Network Address Translator (NAT) Terminology and Considerations"
<http://www.ietf.org/rfc/rfc2663.txt>

There are two variations to traditional NAT, namely Basic NAT and
NAPT (Network Address Port Translation). These are discussed in the
following sub-sections.

Thanks. I was used to Cisco calling that PAT (port address
translation) or "NAT overloading" in IOS.
