Access to modem combo while in bridge mode

I saw the post »Re: [Windows] Can I access cable modem menu through router?

but it was to old to reply to.

Besides two subnet(s) and a static route, does one need to change the RIP setting from disabled to some other setting?

Thanks.

The post you linked to confused me. What router are you trying to accomplish this with? Some router firmwares make it relatively simple to access a modem on the WAN port, usually through the use of an IP alias and a NAT rule (at least the latter appears to be in use on your linked post).

Different ones.

#1 Netgear WNDR4000 without setting a WAN IP to be Static IP with-in the same subnet as the modem combo.

#2 While I don't have this model yet, that I am interested in returning my Netgear WNDR4000 and replacing: Linksys E4200 without setting a WAN IP to be Static IP with-in the same subnet as the modem combo and without loading tomatoUSB.

Note: As to why interested in returning my Netgear WNDR4000 and replacing the it with this router, because I know it supports tomatoUSB.

#3 But I will wait until the tomatoUSB firmware is longer beta to install tomatoUSB on it, which explains number 2 above.

Don't let the beta status of TomatoUSB bother you. I deploy it almost every week and it's trouble free. My parents have a WNR3500L on TomatoUSB that currently has an uptime of over 200 days. It only gets rebooted when the power goes out. Can you say the same about any factory firmware you've used?

As for accessing your modem through the router, try shibby's Tomato mod. I believe there's a place in the GUI where you enter your modem's IP address and it does the work for you.

Do you already have the Linksys E4200? The reviews on Newegg mention that even if you order the non-V2 version that Newegg ships you a V2 anyway. The V2 uses a Marvell chipset that isn't supported by DD-WRT or Tomato. If you already have a V1 then no worries.

Got the verison 1 of it from Stamples.

In this post, I asked how to tell the difference. But I figured it out, comparing the firmware release history of both.

Good score! The reviews on that are pretty good, especially once you get rid of the stock firmware.

You are welcome.

These are the only ways that I know that work (summary, not detailed steps).

#1 With a hub/switch connected between the modem combo and the router, a computer setup to use a Static IP as the modem combo, that computer gets connected to the hub/switch.

a) If that computer has only one NICs it really does not matter what the subnet of both routers are.

b) Only if the computer has two NICs, both routers can not be in the same subnet.

For example one router can be at 192.168.0.1 and the other at 192.168.1.1

#2 Changing the Internet Connection type in the router to Static.

#3 A computer setup to use a Static IP as the modem combo, that computer gets connected directly to modem combo.

#4 Third Party firmware like DD-WRT / Tomato on router, both routers can not be in the same subnet.

Anything else for a modem combo with only one LAN port?

In the thread that I pointed to when I started this thread, it said something about Advanced Routing and to be more exact adding a routing entry and both routers can not be in the same subnet.

Thanks.

Westell 6100F (only only LAN port).

If I was on PPPoE, I have heard/read...

Connecting your router's WAN port to its LAN port is a very bad idea. You just bypassed your firewall and gave LAN access to every other user on your DSLAM.

On the westell vc configuration page what is in the Protocol and Bridge Mode boxes

It appears that the internet connection type you use is not pppoe, so that leaves dhcp or static if you answer my question about the vc configuration page that will tell me what internet connection type is used

In the thread you linked pppoe is the internet connection type
You don't use pppoe and need a different method to access the modem

As addressed on

»Verizon Online DSL FAQ »How do I use a router with the Westell 6100?

Since I have the Red and Black Firmware, In the VC 1 Configuration screen I opened the drop down box beside "Protocol" and selected "Bridge"

What kind of Bridge, not routed bridge as Verizon says - Just Bridge.

I said, I have heard/read if on PPPoE.

Since I am not on PPPoE: Yeah something tells me if I did that, that would not be a good idea.

Before I got a Static Public IP, I was on PPPoE. However my RJ-WAN port router was set to "Keep Alive", so I never noticed the issue that the OP of »[modem/router] How to access 6100G's interface while connected? saw.

If I ever go back to PPPoE (it does not have to be on Verizon), I can try to see if that it is true.

Also I can then check the fix on how to get into the modem combo while another router is handling PPPoE without adding more hardware (ex a hub/switch between modem combo and router), without loading DD-WRT/Tomato, without changing to Static IP with-in the same subnet (PC OR Router Level) - the post by wayjac See Profile (user #544732)

As to what I suspect, I have this odd feeling what the OP started off with and wayjac See Profile (user #544732)'s fix are correct.

Ok, the westell is in bridge mode, so the router must be using dhcp or static for the internet connection type

If the router and the modem use different subnets just typing the modems ip address in a browser address bar will give access to the modem

Correct.

I tried but nope.

I noticed the info at

»Linksys FAQ »How do I access a modem that is connected to the WAN port of a Linksys Router? where it clearly says

quote:
Alternate Method:
If the WAN Connection type is DHCP, then access to the modem should be possible without changing the settings in the Linksys when the Internet is in an "up" state. When the Internet is "down", aka DHCP released, then the modem cannot be accessed.

Is that backwards for modem combos while they are in bridge mode?

OR is there something wrong with my router?

OR that is false/misleading info?

----
Also about that same FAQ where it clearly says

quote:
In PPPoE, access to the modem is not possible through the Linksys.

I gave feedback pointing them to »[modem/router] How to access 6100G's interface while connected? and also to ayjac (user #544732)'s fix in that same thread.

While I don't know for sure what I am reading is true in that thread, I did it because I think it is the right thing to do.

What is the ip address of the modem
What is the ip address of the router

Methods for accessing a modem in bridge mode will be different when the internet connection type is different

I am not logged into DSLR when I am posting this.

LAN IP Address of modem 192.168.1.1, WAN IP N/A (bridged but not routed bridge)

LAN IP of RJ-45 WAN port router 192.168.0.1, WAN IP starts with 71.242

Most consumer routers don't allow for multiple subnets on the WAN interface, which is usually necessary to access the modem in bridge mode. Not all modems can be accessed from behind the router while in bridge mode.

The only modem I have been able to this with, so far, is the Netgear DM111P. It supports RIP, and has a DHCP server for the local interface, that can be turned on and off while in bridge mode. I had full access to it from behind the router. I have not been able to get the same configuration to work with my Embarq (Zyxel) 660, or my current Actiontec GT724R. I have not tried very hard, since the Actiontec has four ports and I can easily connect a laptop if I need to access it.

I prefer the DM111P, as I can get just a little better upload speed with it, but they seem to have a short life span. I've gone through three or four of them in the last couple years.
