Here's the followup...
The DSL modem has an internal address of 10.0.0.1 and normally is just a DSL bridge with the router actually performing all the PPPoE functions.... The DSL modem is not a router.
I've taken the WAN connection cable from my router that normally connects to the DSL modem and plugged it into a temp hub to gain access to the stats. So - this temp hub has 3 connections.... (non-routed) DSL modem - Ethernet connection Router - WAN connection Laptop - Ethernet connection
this works fine, and I can bring up http://10.0.0.1 on the laptop browser and see all the stats: DSL, ATM, Eth, and log
Next - today - I re-enabled the laptop WiFi to see if I could have them both active...
So - I have the browser open with -> http://10.0.0.1/atmstats.htmlRemember this is just a hard coded internal address for the DSL modem and there is no routing paths beyond this since our local network is 192.xx
I open a browser tab and enter -> http://192.168.1.2 and yup - the router logon page is displayed. So - with entering 192.xx - it figures out to use the WiFi connection since we are on the same 192.xx segment as our WiFi IP address.
Next - try a DNS address.... nope - doesn't work - There is no way for the dual IP stacks to figure out which interface to send the request. I can't use the real DNS addresses on the Ethernet 10.xx side, since there is no routing going on that side. The WiFi side has all the required info and routing, but there is no way to give one IP stack "priority" over the other IP stack.
But at least now I can see the DSL modem stats AND the router log at the same time by entering their IP addresses in the browser.
