Can I Translate only the destination port?

jrahm · ‎05-09-2006

I have an access point that is requesting DHCP, and a helper statement on the gw for the remote host 10.1.1.150. The request is on standard udp port 67/68, but the firewall only accepts 546/547 at this time. It will be a week before the fw changes are in, so I was wondering if I can implement a NAT that only changes the port.

TO DHCP SERVER:

Source 192.168.1.21 -> 255.255.255.255 udp/67

Source 192.168.1.17(GW) -> 10.1.1.150 udp/546

Is this possible? IOS 12.3.8(YI3) advanced security image on a Cisco871 router.

I don't think you can translate only the destination port.

Hello

I know that you could use NAT to translate ports.

I'll be testing this and will let you know.

Curious about this solution too.
