AT&T U-verse LAN on eth0 subnet on eth1
I've been using google for the past month trying to find a simple answer for routing. I haven't had any luck, so here I am.
This is what I have:
eth0 is connected to the AT&T LAN from their router/modem.
The modem is 192.168.1.254
The DHCP information giving to the Linux box 192.168.1.175.
By itself, this works fine. Full connectivity to the inter-tubes.
Because I'm a masochist, I work with Cisco phones.
To facilitate this, I added a second network card eth0.
With a static address of 192.168.10.1
And have my (Linux) DHCP server pointed at eth1.
I've been playing off and on with Linux since the days of recompile the kernel daily. But I never got into routing.
I use a MacBook to check connectivity, because it just works and it's simple.
If I connect it to eth1 (though a 5-port switch) It doesn't get any DHCP from the Linux box. Even if I give it a static address 192.168.10.10, I can't ping the Linux box, and vice versa.
Obviously, I'm missing something here.
At the very least, I would like the 192.168.10.x sub-net to work.
Added bonus would be being able to access the inter-tubes from it.
So, which breed chicken do I have to paint yellow and blue, put in a paper bag and wave around over my head?
Using:
/etc/network/interfaces
and
/etc/iproute2/rt_tables
Thank you in advance.
