Ok, I have a linksys router running dd-wrt firmware which is running
dnsmasq. My lan is on the 192.168.1.0/24 subnet. I would like to
be able to access my dsl modem through the router by its ip address
and its hostname. Of course the modem is connected to the WAN side
of the router, so I added a ip address in the same subnet as the
modems address (which is 192.168.2.254) to my router's wan port
(which is vlan2) with this command
ifconfig vlan2 192.168.2.222 netmask 255.255.255.0
I also added this iptables rule to get traffic back
iptables -I POSTROUTING -t nat -o vlan2 -d 192.168.2.0/24 -j MASQUERADE
Here is the strange stuff that is happening. If I try to access the
modem by ip address (192.168.2.254) it seems the modem redirects the
browser to 'launchmodem.com' (which is one of the ways you can reach
the modem by name) before the homepage will appear. Well this
fails. I figured modifying my 'hosts' file on my notebook (running
Vista Ultimate) would solve the problem and it did. So I thought
instead of modifying my hosts file in Vista I would modify the hosts
file on the router then any computer on the lan would be able to
reach the modem. I did that but it seems that Vista isn't using the
host info from the router. So I tried adding these commands to
dnsmasq
address=/launchmodem/192.168.2.254
address=/launchmodem.com/192.168.2.254
address=/www.launchmodem.com/192.168.2.254
When I do this I can ping the modem FROM THE ROUTER all three ways
i.e 'launchmodem', 'launchmodem.com', and 'www.launchmodem.com' I
can also ping the modem from the router all three ways with these
added to the router's hosts file. However, from my notebook I can
only ping 'launchmodem.com', and 'www.launchmodem.com' but NOT
'launchmodem' (host not found). Another oddity, I can only reach
the modem in my browser with 'launchmodem.com' not with
'www.launchmodem.com' even though I can ping 'www.launchmodem.com'.
Can anyone advise me on what is going on here and how to
troubleshoot/fix?
Thanks!

I think that the Windows ping command does not always use DNS to find
the host. ?Sometimes it uses netbios methods, which usually means
trying a broadcast and see whether anything responds. ?Maybe pinging
launchmodem. with a final dot will change it? ?Or you could try
nslookup, though that has its own set of problems. ?Best would be to
test with a Linux-system instead.
Another

'launchmodem.com' not

Sounds to me like the modem is rejecting that domain when it gets the
http request.

If in doubt, run wireshark.
