Is it possible in any way to access a modem while in bridge mode?

[riahc3]

Just wondering, is there any way to access a modem while in bridge mode?

Most cable modems have an internal IP address that can be used to access them while in bridge mode. Motorola and Arris modems use 192.168.100.1 or you can look up your specific modem online to find its address if that one doesn't work.

Its a ADSL modem and (supposing it is 192.168.100.1) I could still access it even though my network is 192.168.1.x ?

Yes, you should be able to. You just need to find the correct IP address for the brand/model of the modem that you have.

Doing a ping scan with nmap on my pc connected to a port with port mirroring enabled for 192.168.*.* should be enough right?

That should do it, however my cable company disables the page when i am connected to them, if i remove the coax I can hit the page but as soon as i plug it in i lose access

This is a ADSL modem, not cable. It should be the same...

It isn't disabling the page, it is a local IP, so once you connect to the wider internet, since the modem is outside the router, the router cannot route to it as it isn't in the DNS tables you are looking at when connected to the internet. Disconnect and you have no DNS lookups and all there is is that local IP sitting right outside your router.

Actually they disable the page. The modem handles the "routing" if the maintenance page is enabled. Mine is 192.168.100.1. No where on my network do I have any internal routing for that. Nor can I ping it and a tracert appears to go off to the net and die at a internet router. The modem basically intercepts that IP address. I have had the same modem on Comcast and Wide Open West and like RadiclDreamer, Comcast blocks the page in the config xml (you can grab it via an unconfigured router and see the [paraphrased]<maintpage>0</maintpage> right in the XML. Same one on Wide Open West works and from that XML you can see <maintpage>1</maintpage>.

Also Comcast is known to move the intercepted IP also. I have had it be 192.168.100.1 on WOW and 10.10.10.10 on Comcast.
