Hi,

I bought a GNet BB0060B MoDem on the advice of my
ISP but they refer me to GenTek for configuration
and support... Right now it works in conjunction
with a LinkSys BEFSR41v3 router which handles the
PPPoE protocol (since i don't know how to make it
self-sufficient yet). In any case, i have access
to the router's HTTP User Interface (192.168.7.2)
but when i try to get that of the GNet ADSL MoDem
(192.168.7.1) there's just no reply. My question
is this: what should i set in the router to gain
simultaneous access to both HTTP User Interfaces?

Are there any instuctions with the modem that says it has a web interface you can access? Usually there is nothing for you to modify on the modem.

It would also appear that you do not have the correct address for the modem. Usually .1 is your workstation gateway address and that is your router.

Your modem would be in a totally different subnet than 192.168.x.x. Usually it would be in a class B address range not a class C address range.

Routing works like this;

You have your ISP provide your WAN interface of the router with a ip address. This address is passed from a dhcp server to your router.

In your case with PPoE you have to have your router set with a user name and password [provided by your ISP]. This completes the WAN interface.

On the LAN [local area network like your pcs] side you have your router provide YOUR pcs with a ip address via dhcp [it can also be a dhcp server] This is your 192.168.x.x address range. You access your router's web interface from your LAN.

The lan ip asubnet [range of ip addresses] and the wan ip subnet HAVE TO BE DIFFERENT FOR ROUTING TO TAKE PLACE.

Otherwise you are just bridging and that is a tale for another day.

Hi,

It's the first thing i did so, i used this feature
previously... Here's one reference out of a few:

http://ftp.gentek.com/gnet/ADSL%20Modems/BB0060B/Manual/Quick%20Start%20Guide%20-%20ADSL%20Modem%20Router%20-%20Ethernet.pdf

Perhaps i should have specified that this MoDem is
also a router with plenty of bells and whistles to
play with... The unit has Bridge and Route modes.

W > It would also appear that you do not have the
W > correct address for the modem.

Well, that's the default address and it works if i
use the unit alone but then i have no INet access:
i must configure it with my UserName and PassWord,
which worked just fine before i switched from Bell
Sympatico to Vif (those who won't give support)...

W > Usually .1 is your workstation gateway address
W > and that is your router. Your modem would be
W > in a totally different subnet than 192.168...

I had to change the Windows DHCP IP to fixed IP to
access the MoDem at all and i got tired of this as
the router made me change my Windows fixed IP back
to DHCP IP when i put it back. Perhaps there's a
better solution but using 192.168.7.x seemed OKay.

W > Usually it would be in a class B address range
W > not a class C address range.

All right, then what do you propose for my MoDem's
address so that i can go thru the router and reach
it? As i wrote, what should i do to the router to
access *BOTH* HTTP User Interfaces simultaneously?

W > In your case with PPoE you have to have your
W > router set with a user name and password...

That's only temporary, i must return the router as
it is my sister's router and she's moved lately...

I may come to buy a hub, switch or router that has
many more bells and whistles but this will have to
wait. Yet, i still wish i could reach both GUIs.

W > The lan ip subnet... ...and the wan ip subnet
W > HAVE TO BE DIFFERENT...

The router's and MoDem's IPs can be changed easily
but it's what will come next that makes me wander.

I don't think you can get your modem startup page while it is connected to the Linksys. Can you get to the modem startup page when connected directly? Did you power cycle after you changed the settings of the modem. Your instruction were explicit in changing the settings between the setup mode and user mode. You have to restart the computer when you change modes or have 2 different computers. I think it might be better in starting over in resetting the modem. Remember you have to repower each device that gets a setting if you change an upstream device.

Hi,

WF> I don't think you can get your modem startup

I like Wanderer's crash course over WAN vs LAN and
Class-B address range vs Class-C address range. I
have my doubts about getting thru the router while
it manages PPPoE in this MoDem but what if there's
a way to disable the router part in the router and
leave routing to the GNet MoDem/Router instead?...

WF> Can you get to the modem startup page when

Yes and yes.

Setup vs User mode? I'm afraid i'm not following.

WF> You have to restart the computer when you
WF> change modes or have 2 different computers.

I reboot the PC if the "Repair" function fails and
deactivating/re-activating the connection/adapter
also fails. The MoDem and the Router are another
story: they're both connected to an independant
power-bar that i can switch on and off at will...

Hi Wanderer,

This is as far as your late answer has brought me:

http://www.dslreports.com/forum/remark,14190712

Thanks for the insight! Please don't hesitate to
contribute with more input if you feel like it, i
found your post stimulating, euh... I don't know
what to make of it but here's another link i got:

http://www.dslreports.com/forum/remark,13398746

All this stuff might inspire one more thought or
two, i post my update here as i have found hope!

Am I reading this right you have a router modem and a linksys router? And you want to use them together?

The router modem will provide a dhcp address to the wan interface of the linksys. It appears it will be in the 192.168.x.x range.

So to be able to get to the modem interface AND the router interface all you have to do is modify the LINKSYS LAN interfaces dhcp scope. Instead of 192.x.x.x use 200.200.0.x

This will allow you to access the modem interface at 192.x.x.x and the linksys interface at 200.x.x.x

That work for you?

Hi Wanderer,

W > ...you have a router modem and a linksys
W > router? And you want to use them together?

I'd rather use the LinkSys router as a switch only
until i get a proper replacement device but i just
couldn't get my GenTek/GNet MoDem/Router to manage
the PPPoE connection autonomously. Until today, i
depended on this LinkSys router to handle PPPoE...

W > The router modem will provide a dhcp address
W > to the wan interface of the linksys.

Each day carries its load of difficulties; at the
moment, i'm able to make the MoDem/Router connect
without having an error message scrolling down in
a continuous way on the terminal i attached to its
RS-232 console port but i still need to define the
IPs and NetMask manually... On top of that, even
when i can live with my settings and i finally get
them saved (to a file and permanent memory), PPPoE
fails to complete after i reboot it! I can sense
hours of pure ecstasy coming in the next few days!

%-b,

I'm afraid not, i tried to reconfigure the router
as follows: Local IP Address= 200.200.0.2 while
SubNet Mask= 255.255.255.0 with Local DHCP Server
Enabled. The DHCP Address Range was 200.200.0.1-
200.200.0.6 but when i tried DHCP configuration it
ended with a "limited or non-existant" adaptor or
TCP/IP connection... Anyway, thanks for trying!

:)
