Getting NETGEAR Cable Modem Gateway CG3000D-2 to coexist with FRITZ!Box 7270
Posted on 2013-11-25
Hi Experts,
I have been running a FRITZ!Box 7270 as an ADSL modem, router etc.
I have just added a NETGEAR Cable Modem Gateway CG3000D-2 (because I have switched from ADSL to cable Broadband).
It's on a different subnet (192.168.0.x) to the FRITZ!Box (192.168.1.x)
These are the LAN Settings for the NETGEAR:
LAN IP Address: 192.168.0.1
Subnet Mask: 255.255.255.
DHCP Server: No (was Yes, but I want to change it to No, so that the FRITZ!Box does DHCP)
I have tried changing the settings to:
LAN IP Address: 192.168.1.254
Subnet Mask: 255.255.255.
DHCP Server: No
But when I click the Apply button, I get this error:
"LAN IP address and Guest LAN IP can't be in the same subnet"
What's the "Guest LAN IP"?
Regards,
Leigh

Each of those devices wants to 'own' the network it is connected to. Putting one on a different subnet will not help. They would have to be completely physically different networks.
I actually have that setup here with DSL and Cable. I have several computers with two NIC cards, one connected to each device. They have to be setup so that only one of them has a 'gateway' defined because Windows will just get confused if you enable the gateways on both of them.

Thanks, Dave, for your comments.
I did get it work, here's how:
Changed Fritz!Box Home Network | Network | Network Settings | IPv4 addresses:
IPv4 address: 192.168.0.254
enable DHCP Server range: 192.168.0.20 - 200
See User Manual, Section 5.2:
Fritz!Box Internet | Account Information | Internet Service Provider | choose "Existing Connection over LAN"
connected Cat5 cable from Fritz!box LAN 1 to cable modem
All working now!
