Netgear CM1100 V2.01.02 - Listening on both 192.168.0.1 and 192.168.100.1
Hi, I have a Netgear CM1100 using firmware version V2.01.02. I did a routine scan on my network using NMAP and noticed that the modem is listening on both 192.168.0.1 and 192.168.100.1. I know that...
Was NOT able to access the modems web page at 192.168.0.1 whatsoever.
Yes that's correct. I am directly connected to the modem. There is no external router hooked up to the modem.
Are both accessible if the external router is connected and the router is set for .0.1? I presume that should be accessible then. The .100.1 should be though.
Thanks FURRYe38 for the input. So just to be clear, you would like me to attach the external router directly to the cable modem and change the external router's IP (currently .1.1) address to .0.1. Then attach my laptop to the external router and try to access http://192.168.0.1. correct? Is the expectation that I would go to my external router's admin portal? I will give this a try and get back to you.
Without the external router hooked up right now, if I access http://192.168.0.1 from a browser, I get a prompt for login credentials (which looks similar to http://192.168.100.1) but I am unable to log into it. I tried my admin credentials as well as the default username and password (admin/admin). Nothing worked.
Yes please.
Hi FURRYe38 , when I attached my external router to my modem, and then attached my laptop to the external router and try to access http://192.168.0.1 , I get the admin portal for my external router. I made sure to change my external router to have IP address 192.168.0.1 as requested.
Just in case it helps identity why I am seeing the mysterious IP address 192.168.0.1 on my network, here is what I get when I use curl to dump the pages. This is what I see when I am connected directly to the modem without any external router.
