Yes, I'm familiar with that thread. It's very good, but has problems which I've already tested and encountered

1. Doesn't work for single port modems

2. Generates self-flooding of network from modem back up to router, blocking all download activity for about 60-90 seconds, every five minutes or so.

3. One or more of the methods needs another small switch between the router and the modem, requiring more equipment.

4. Doesn't solve the static ip addressing problem I'm trying to solve here.

Thanks, though.

As I mentioned, I can access the modem ip config pages when it is in bridged mode if I connect to it directly with the computer (setting the computer ip subnet to include the modem ip address). But can't do it with the Linksys in between.

So it's not generally an issue getting to the modem, it's getting the Linksys to route it to the modem.

Is there some reason you think the lInksys can't do this? The link I included indicated it could. I'm not familiar with DD-WRT replacement firmware.

Hope this helps/is not too confusing. If you’re interested in doing something like this, let me know and I’ll provide more detail.]]> http://www.dslreports.com/forum/Re-Windows-Access-bridged-modem-configuration-behindin-front-22639976 Wed, 01 Jul 2009 14:03:58 EDT http://www.dslreports.com/forum/Windows-Access-bridged-modem-configuration-behindin-front-of-22638202
OK, here we go on what appears to be a very old topic: accessing the configuration and status interface of a bridged ADSL modem that is separated from the computer by a router. (Whether it's behind or in front of the router is a matter of perspective I think):

Computer LAN NICs---Switch---Router---ADSL modem BRIDGED mode---Internet

The ADSL modem web GUI configuration interface is accessible in all cases when the computer is attached directly to the modem:

Computer NIC---ADSL modem BRIDGED mode---Internet

The most relevant of many threads I've found on this topic is this one:

»[Windows] Can I access cable modem menu through router?

In that thread, it is "Muiredised" (what kind of a handle is that?) who has described the desired solution best. Unfortunately, it hasn't worked for me, as it didn't work for any others in the thread, as near as I can tell.

I have tried his static routing solution with three different ADSL modems in bridge mode, and experimented with a number of gateway addresses as well. Details are below. It is unclear to me why a bridged modem will present (or allow) more than one ip address on a single physical port, or rather will listen for, recognize and peel off its own ip address on traffic to the internet.

The observations of OZO in that thread make the most sense to me, tho I'm hoping it's possible using static routing in the router (not the modem) that this will work. (I might also note that tubbynet's evidence of it "working" by showing the ping data is not conclusive. The ISP can have this address available on its network, which appeared to be the case for me that I discovered with tracert.)

Any clarification of this issue would be greatly appreciated.
