port 53 redirection

Hello All,

Is there any way I can redirect all outbound port53 (TCP/UDP) traffic to a fixed ip address on the same port?

I have a cisco 867.

Regards,

Amit

Hello Michael,

Thank you for this information. But I am trying to achieve soemthing else over here.

I want to redirect any traffic going out on port 53 to a public ip address on port 53

tcp 0.0.0.0 53 >>> 202.90.XX.XX 53

udp 0.0.0.0 53 >>> 202.90.XX.XX 53

I can do this on other vendor devices.

eg: on a mikrotik router board this is what i use

add chain=dstnat action=dst-nat to-addresses=202.90.XX.XX to-ports=53 protocol=tcp dst-port=53

add chain=dstnat action=dst-nat to-addresses=202.90.XX.XX to-ports=53 protocol=udp dst-port=53

Any help would be much appreciated.

Regards,

Amit
