Ignite WiFi Gateway – Change/Disable DHCP/DNS/IPv6

Incomplete DHCP4 functionality in Technicolor CGM4140COM:

 

Hi all, I was getting an error message when assigning DHCP reservation for my device, and then when I try to assign it again I get a message that the IP address had been already reserved. But the reservation didn't work and there's no way to view DHCP reservations. 

 

So I decided to run my own DHCP server, but can't find a way to disable the built-in DHCP4 server in the gateway. Does anyone know how to do it?

@aeromedved There are are certain functions that you cannot disable on the Ignite gateways, and DHCP is one of those.  Nor can you disable IPv6 or specify alternate DNS servers.  The only thing that you can do is to enable "Bridge Mode" and then install your own router/firewall.

Disabling IPv6 on Ignite - Workaround?

 

When we were on the Hitron router, we could disable IPv6 and this would cure some issues within our Windows domain.  Having moved to Ignite, the issues have returned.  Unfortunately, the Ignite gateway doesn't permit us to disable IPv6.  (We need to have IPv6 enabled on the machines, though.)

 

I was wondering if it is possible to connect a router to the gateway, without bridging the Ignite gateway.  The reason for this is that I want support from Rogers for TV and internet issues, which can't happen if bridged.  By having the router, I could disable IPv6 on it and can connect my Windows devices to it and my other devices to the "Ignite LAN".  Windows devices don't need to talk to non-Windows devices and vice versa.  I do need to be able to VPN to a Windows server, however, so port forwarding could be an issue.

 

Has anyone tried this?

You can do this.  It's not a great solution because any systems that are connected to your router, that access the Internet, will be traversing two IPv4 firewalls that each perform network address translation.  This "double-NAT" situation is known to cause issues for certain applications and may cause problems for your VPN connections.  You will have to test to see whether or not this configuration works.

 

It's too bad that you cannot configure static routes in the Ignite gateway because otherwise, a better solution for creating an IPv4-only island on your in-home LAN would be to configure your internal router as a simple IPv4-only router, with its firewall disabled.  Unfortunately, this configuration will not work because there is no way to configure a route in the Ignite gateway, so the Ignite gateway will not know how to route packets back to your IPv4 island.

I've browsed the settings in both my gateway and the Rogers Ignite hub, I'm able to view both DNS servers but it doesn't give me an option to change them. How can I change my DNS servers?

Not in the gateway. You can set your ip and dns as static in your ip settings of your device.
