That DSL Modem is also a router. The westell dsl modems are just like this.
They look like a modem with 1 lan port, but they are a modem/router.
There's a config page you'll have to get to in order to switch it to a
bridged ethernet as Al mentioned below. On my westell, it was
192.168.0.2/config. Just using the modem IP doesn't reveal this page; maybe
the company didn't want people changing settings.
I did see one posting on the web about using this address:
192.168.1.1/mmadv/advindex.htm.
Good Luck

You need both TCP Port 80 (IIS) and TCP Port 3389 (Remote Desktop aka
RDP)
open/forwarded through any firewall or router the PC you want to connect
to
is behind.
I opened both ports (actually used an alternative to port 80).
So, if you go to the http://www.canyouseeme.org site while on
that PC does the test pass? Meaning can you pass both the IIS and RDP
port
tests?
It did not pass. Then I tried removing the routers between the DSL modem
and
host computer and canyousee.org still didn't pass.
If not, can you at least pass the RDP port test?
I could not get it to pass 3389 or 80 (or my substitute).
Be aware some DSL
modems are also routers and either you need to open/forward the
appropriate
ports or configure the modem into a bridge mode, ie. disabling its NAT
function. Check the users manual for help with that.
I don't think this is a router because there is only one LAN port in the
back. I also checked the advanced settings and there doesn't appear to be
anything I can change.
Also make sure your calling the correct public IP. Note that with most
current consumer grade routers it is *NOT* a valid test to call the PC
from
another PC on your local network using the public IP of the modem and/or
router.
I had someone try connecting to my IP address from another location and
they
got a "server error".
Also note that some ISPs block TCP Port 80 incoming because running a
web
server (ie. IIS) that is publicly available is a violation of a
residential
account terms of service. Check with your ISP about that...
I substituted a port for 80. I configured my routers/firewall for that
port
and I am able to connect using my internal network 192.168.0.3:xx/tsweb.
It sounds to me like that DSL modem is also a router. With the computer
connected directly to the router what IP is reported if you go to
"Start -> Run" and type cmd at the command window, then type ipconfig at
the command prompt? Is is a 10.X.X.X or 172.16.X.X or a 192.168.X.X
address? If its one of those IP ranges then you need to find a way to put
the DSL modem, which is also a NAT router, into a bridge or pass through
mode of operation, ie. the built-in NAT is disabled. Check the users
manual for help with that or check with your ISP.
