When going from gateway to bridge, my planned sequence is as follows:
make a backup of the gateway mode config file in case I need to go back to gateway mode.
do a factory reset (to clear out all my personal settings and passwords)
change from gateway to bridge using the straight forward one-step Rogers instructions, ie go to Basic/Gateway Function, toggle the Residential Gateway Function to 'Disabled' , and let it reboot.
connect and power up a DCHP router.
1) Once in bridge mode, is any part of the admin page accessible at all? I assume no, and no more IP address for the unit.
2) Is there any password available anymore on a bridged Hitron?
3) When connecting a DCHP router to the Hitron, for the first time, does the Hitron need to connected to a router with a 192.168.x.x IP address, or can the router IP address be anything I want?
>> Before you disable the gateway mode, disable the NAT function (distribute LAN IPs).This will pass through the internet IP to your 3rd party router. If you do not do this, your router will pick up the 192.168.0.x IP and will cause issues with other applications such as VoIP.
My CGN 3 in bridge mode flashes the activity light but does not have the other light on....I am not sure I have seen it even for the 2 hours I used the device in gateway mode before going to bridge mode.
It would be good if the next firmware update to the CGN3 just turned all the features of the device. I use mine in bridge mode as IPV6 facilities are turned off in gateway mode. I use Roger's 6RD service which in most routers is part of the IPV6 setup.
