[NCLUG] DSL modem + Wireless Router setup

[Chris Funk]

Hi Luke,

Is there an admin interface on the dsl modem?  If so, log into it and look for a bridge mode, enable that and you should be good to go.

HTH.

Chris

<disclaimer>Technically this is not a Linux question but it's close.
Closer than Windows, further than FreeBSD. It's UNIX, at least,
because the machine has Mac OSX and if I get it to work my Fedora 5
machine will be online, and it's also a configuration that isn't
supported by the gravy-sucking Windows-centric vendors, so I figured
some NCLUG people might have seen something like it.</disclaimer>

I just got DSL and the "modem" is a Westell Model 6100. As configured
by Verizon for my line its DHCP server provides me an IP address like
192.168.1.(46,47). It works fine when I connect my PC directly to it.

But I want to connect a whole bunch of machines to it. So I got a
Linksys WRT54G wireless broadband router and plugged its' "WAN" port
into the back of the Westell "modem". Then I connect my PC to one of
its "LAN" ports (I don't even want to think about wireless yet) and
its DHCP server hands me an IP address like 192.168.1.100. I can
connect to its admin page very nicely.

The problem is that I can only connect to it. I can't ping or
traceroute anything out there in the world, like nclug.org.

My suspicion is that the wireless router is confused because it has a
192.168.1.xxx net on both sides. But that's just a clueless
TCP/IP-unsavvy idiot's opinion who never quite did figure out what a
"route" is.

Anyway, if anyone has ever figured out a problem like this. I'd
appreciate the benefit of your wisdom.
