Re: How to access cable modem "in front of" firewall

Got it. Pretty boring though.
I spent all this time thinking about how to do it without ever trying
it. Now that I'm home I gave it a try and without changing anything
after the default install of IPCop I can view the modem's status page.

I can reach 192.168.100.1 from 192.168.1.49 with a NM of
255.255.255.0.
Can't imagine how.

Now I almost wish it didn't work so I could figure how to make it
work.

Thanks for the dialog anyway, Todd.

My LAN is on a different subnet (192.168.1.1, 255.255.255.0) from the
cable modem (192.168.100.1)

I'm pretty sure adding the "route add ..." will get me out of the
firewall and to the modem (as opposed to "through" the modem to talk
to the modem it will have be able to get back to me.

I'm not sure how to make that part work.

Are we dealing with a software or hardware firewall?

Another issue possibly at play is that 192.168.100.1 being an RFC1918
"private" address that shouldn't hit the internet, may not get routed
by your router to the WAN interface. I imagine implementations of
that egress filtering vary.

Not being familiar with which firewall you're dealing with, I can't
say more but to guess at that maybe being at play.

There should be another IP by which you can talk to your cable modem.
Check out the broadbandreports.com forums and see if anyone talking
about your provider specifically might have it included in a post, or
a procedure on how to figure it out.
