MAC Address Spoofing Can I Do it on a Cisco Router?

[eric_clapp]

Please help,

I have a Cisco 871W router and need ideally to spoof the mac address of me previous router to avoid changing the DNS records for my domains.

Any advise would be greatly appreciated.

I am not familiar with the 871W router. But most IOS based routers give you the ability to change the MAC address of interfaces that have a MAC. Check in interface configuration mode and see if there is a command "mac-address". If it is there it should give you the ability to have the router use the MAC address of your previous router instead of the burned in address of your new router.
