I have a the Motorola 2210-02-10NA DSL router. On the LAN side, I have a Linksys wrt54g, running OpenWRT.

I would like to configure this device to be in bridged mode, so that I can utilize the abilities (Firewall, etc) of my Linksys wrt54g.

However, if I enable 'Bridged mode' per the instructions at http://sonic.net/support/dsl/cpe/motoro ... nfig.shtml I am no longer able to log into the 2210-02 router, as it's on a different network), and cannot view the DSL statistics on this device (Line attenuation, etc).

Is it possible to configure the 2210-02 so that it is still in bridged mode, but so that I can still log in and view the DSL statistics?

Thank you in advance,

Hello Stefan,

You should be able to connect directly to it and statically set your IP address to 192.168.1.x with the subnet mask of 255.255.255.0 and the gateway of 192.168.1.254 and then you should be able to access it. Otherwise, there is no way that I am aware of to allow access to the interface through your router and have it set into bridge mode.

one possibility is to place the modem on its own subnet on the WAN side of the router and create an appropriate second interface (IP address) on the WAN side of your router

example, using DD-WRT, Tomato, openWRT or their derivatives; scroll down to 'Accessing a bridged modem via the router'
http://www.linksysinfo.org/forums/showt ... hp?t=63486

you can try to implement the same concept with whatever current firmware on your router

say you give the modem the address 192.168.0.1, then eg. you want to make the WAN side of your router have (in addition to the Sonic public IP) an address like 192.168.0.3; hence from your 192.168.1.x LAN you can access your WAN side modem at 192.168.0.1

on DD-WRT, Tomato, etc, on the Wan-Up script page: create the 192.168.0.3 WAN IP with two script lines
sleep 5
ip addr add 192.168.0.3/24 dev $(nvram get wan_ifname) brd +

on the Firewall script page: create a firewall rule (not sure why but it seems to work without this firewall rule in Tomato)
iptables -t nat -I POSTROUTING -o $(nvram get wan_ifname) -d 192.168.0.0/24 -j MASQUERADE
