NAT help

whiteford · ‎02-26-2009

Hi,

I have a cisco ASA 5520 and connected as a trunk I have a Cisco 3750 with a VLAN for our WAN office.

This remote WAN office has a router which uses DHCP relay back to our LAN where the ASA is, we don't manage the router and have to pay money for any change (silly or what).

ANyway I need to change the DHCP server they point to and thought I Could NAT the one the point to now to the new one, is this possibe?

I did try add a NAT what it didn't work.

if the relay configuration on the router is pointing to the real ip-address of your DHCP server - Natting will not help.

a rough diagram would be helpful to understand your requirement.

"if the relay configuration on the router is pointing to the real ip-address of your DHCP server - Natting will not help. "

This is exactly what I'm doing.

I will try and get a diag done. Basically:

LAN

ASA - 3750-(VLAN7) - Remote WAN

Router

Internet
