OK. Then then modem is doing NAT.

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

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.

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.

Grrrr....

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.

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...

It's possible that I am messed up in my thinking about this since I am
somewhat new to networking.

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.

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.

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.

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.

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

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