CISCO 837 CONNECTED TO A NETGEAR

Hi, My Internet provider, provided a Netgear Router Model no: VMDG280 Via a coaxial cable.  The Netgear also has 3 Eth ports on it.

- I have connected my Cisco 837 router via a x-over cable to the Netgear router.
- My Cisco 837 has SDM 2.5 software running on it.
- I know how to Disable the DHCP on my Netgear router
- I have allocated temporarily an IP Address on same subnet as the Netgear just for the purposes of being able to access the Cisco 837 and I can successfully.

I wish to know how to allow the Cisco 837 via SDM 2.5 run Dhcp instead of the Netgear so that I can then 'TEST' and configure the box just for practice?

Can anyone advise?

Hi jmeggers,  Yes I know how to configure the DHCP via the CLI and successfully tried it via the SDM and it was successful by also adding dhcp config to the Cisco 837!!!!

After the above as not configured the other settings I lost my internet connection.?

I clicked on the LAN part to detect the Eth ports but it appeared to do a search and stop.

The connection that I was expecting to be detected on the Cisco 837 was the x-over cable for port 4 of the Cisco 837, but it did not!!

Saying that I've just now realised I should have 'Disabled' the Dhcp and removed 'mac' from the Netgear list then saved settings, then tried to detect the Port 4 on the Cisco 837.....

Dont know why I forgot that!!
I have software for 'Wireshark' but will use that later as just trying to understand be able to do the practical of making another router priority due to the way I've got it connected as my Cisco 837 has an 'ADSL' port and cannot use it because my Internet Provider has provided the 'Netgear router' which has a 'Coaxial' cable attached!!
Hi jmeggers,  My Cisco router 837 is now set as the primary Dhcp as the 'Netgear router' that is directly connected to the internet is also 'Disabled'.

Qns1. My laptop that I plugged into the Cisco 837 Eth port is up and has been allocated an address via DHCP but I have no internet access - Why?

I mentioned previously that the 'LAN' tab on the Cisco 837 just searches but does not open up what ports are detected as this is what I think is the problem hence no internet connection on my laptop!!!!

Hi deepdraw,  I have not removed nothing yet as the only things set are the following:

The config to allow access to the Gui
Dhcp configured

- Bear in mind my direct connection to the internet is my Netgear router via a 'coaxial' cable, with 4 Eth ports
- The Netgear Dhcp has been disabled, although when I disconnect the x-over cable the Netgear router still has the ability to allocate IP Address.  After Disabling the Netgear and 'Apply' changes, I have not logged off the 'gui' or rebooted the router!!

- My other router is a Cisco 837 connected to the Netgear via a x-over cable

Hi experts if its ok I wish to come back to this thread at a later date as wish to resolve the last issue I had when trying to connect as a temporary measure, my Residential Netgear box, which is my direct internet connection, via my Cisco 837, just for the purposes of learning and configuring 'sdm', but the issue I had was that it would not give me an internet connection.

What I remember as my cisco 837 is not currently connected was that I think I was supposed to link an 'eth' connection or something within the 'sdm gui', as was connected via the 'eth' port of the cisco 837, but was not sure what I was supposed to do first as tried and failed.
Hi ive read through my comments again with more clarity and ive decided that the expert advice is enough for me to now close this thread.  thanks for your patience.
sound advice.
