Ready for Take 2 :-) ? With the additional information you've given, and
a read of the manuals for the Zoom, the DI-624, and the WRT150N, I have
a better understanding. Key points:
- you want to have all four LAN ports on the WRT150N available for LAN
devices
- the Zoom does not seem to have a bridge mode
- although you can turn off NAT in the WRT150N, it requires you to set
up routing, which is a PITA and I'm not convinced it works as desired
- double NAT is normally considered evil, but is really only an issue
when you have servers or gaming consoles that must be addressable from
the "outside" - I assume you have neither
My approach:
- doesn't matter whether the modem has Auto DHCP on or off, you won't
use DHCP there
- configure the WERT150N as follows:
Internet Setup
- Internet Connection Type: Static IP
- Internet IP Address: 192.168.1.2
- Subnet Mask: 255.255.255.0
- Default Gateway: 192.168.1.1
DNS1: whatever your ISP provides, or Google's 8.8.8.8 [if you don't
consider Google evil]
DNS2: whatever your ISP provides, or Google's 8.8.4.4
NOTE: you could have used DHCP here, but I like knowing what IP addresses are
actually in use.
Network Setup
- Router Address: 192.168.2.1
- Subnet Mask: 255.255.255.0
- DHCP Server: Enabled
- Start IP Address: 19.168.2.100
- Maximum Number of Users: 50
- Time Settings: optional, normally irrelevant
NOTE: you could have used any subnet address here (even 192.168.1.x, same as on
the WAN side), but keeping it different from the LAN segment between the Zoom
and the WAN side is to avoid confusion.
Now connect the Zoom's to the WRT150N's WAN port, and you should have
four LAN ports ready to go.
Let's see if this gets you back on the air as desired. As for how the
DI-624 handled this before, I assume it was a functionally identical
configuration, with double NAT (which had no impact on your use).

Thanks for the responses.
See inline comments:
Most modern ?modems?, whether DSL or cable, are a combo modem/router,
and a few details you?re provided do confirm that?s what you have.
From what you?re saying you were using some of its router functions
previously with the DI-624 (for example, NAT), which makes me wonder
what you were using the DI-624 to do; the two possibilities are to
provide extra Ethernet ports (i.e., acting as a small switch) and to
be a wireless access point.
Yes, my modem is a router. But with, to be technical, one "inny" and
only one RJ45 "outy". So the DI624 acted as a switch and wireless
access point. It was connected to the modem via its WAN port and my
ISP at the time helped me set it up. Unfortunately I can't find a
backup of the conf file for it. I do have the original conf file for
the modem if that would help.
So I?ll presume that the ?modem" should continue to be your router
(configured with PPPoE username and password to get your Internet
connection, and providing NAT and DHCP), and the WRT150N is just a
switch / wireless access point. Most Linksys firmware is pretty
similar, so configure the WRT150N as follows (assuming LAN subnet is
192.168.2.x and modem/router is 192.168.2.1, adjust as necessary):
First thing I did was switch the WRT150N to IP 192.168.2.1 so as not
to conflict with the modem on 192.168.1.1How do I check the LAN
subnet? Is this through Control Panel >>Local Area Connections??

* Wireless / Basic Wireless Settings [as present in the WRT150N]
- Network Mode: Mixed
- SSID: your wireless network name
- SSID Broadcast: your choice, normally Enabled
Yes, did that. The WRT150N is working fine as an access point but the
double NAT is messing things up with the LAN.
* Wireless / Wireless Security
- Security Mode: WPA2 Personal [some older PCs don?t support WPA2, if
so then just WPA Personal]; with AES if an available option
- Passphrase: your wireless password
Security? I'm from the You-S-A. Us country folk use double-barrel
security. ;)
You cable one of the WRT150N?s*LAN* ports (not the WAN port) to the
modem, and you have the other three available LAN ports on the
WRT150N and its wireless as your LAN. If you wonder why you're
connecting to the LAN side, not the WAN side: WAN->LAN does NAT,
which is already done in your modem, you don't want/need a second
level of NAT.
I'd rather use the WAN port same as the DI624 did and free up all four
LAN ports and not have to buy a switch. How did the DI624 manage to do
it before? Maybe that's a "bridge" which I don't understand.
If I?ve misunderstood anything, let me know and I can revise my
advice. Also, I?m curious about the make/model of your DSL modem.

P.S. I have DSL at home, with two separate routers of my own. Most
combo modem/router devices can operate in one or both
(simultaneously) of two modes:
- router, providing NAT, DHCP, etc. as you seem to be doing
Yes.
- bridge, providing a direct PPPoE ?interface? for your router to
connect via PPPoE
My DSL modem (Bell [Canada] Internet, previously a 2Wire 2701, now
upgraded to a Sagemcom 2864 for 15/10Mb service) operates in
both/hybrid mode, but I ignore the router side and just connect
multiple PPPoE-configured routers to it (Bell's service will deliver
multiple PPPoE connections/IP addresses using the same
username/password, I?ve had up to five for testing routers but only
use two now - one is my personal home network, the other my home
office network).
I don't understand the "bridge" function. Does that mean that I can
bridge the modem, bypassing its router functions and use the WRT150N
to do the NAT, etc.?
