Cisco 867 Bridge Mode 'dumb mode'

Hi,

I need to be able to configure a Cisco 867 in bridge mode so that it will pass the IP address allocated by the ISP to the FE0 port as I use another device in the network for firewalling and routing. The ISP username and password would be best to remain in the 867 and not the firewall device.

So far I am only able to get it to connect successfully in 'router mode' and various examples I have found online are of no use.

It would be much appreciated if I could get a brief example of what I need to do to achieve bridge mode on the 867.

Thanks.

Ok, what type of ISP do you have ? DSL, Cable, MetroEth?

It is a standard DSL connection. I have a static IP address from my ISP, however I have been told by them the router/modem can be configured with static or dynamic settings. If I configure 'dynamic' at my end, the ISP presents the static settings anyway.

Basically I need the IP address that is on the ATM0 port assigned to the FE0 port. FE0 won't configure as bridging for some reason, so im guessing I need the VLAN1 to get the IP from ATM0? The Cisco box needs to be basically transparent. FE0 connects to the firewall applicance. Currently I have a Netgear doing the job in 'modem' mode, and it assigns the WAN IP to the LAN port on the back of the modem.

In this case you need a modem, not need router....

So there is no way to turn/program this router into a modem as such and use it that way? I realise it is a waste of a Cisco box, however it is a bigger waste leaving it sit on the shelf...

Yep, or you make STATIC NAT for translating to public address, to firewall leg!
