NAT for subnetworks from router to Core LAN

lveraza2010 · ‎09-17-2010

Hi,

I’m working with a L3 Core Switch with 4 VLAN´s and 4 sub networks(10 network). I’m using only 10.0.0.0/8 network in all LAN and 172.16.X.X in all WAN.

I have a WAN VLAN (VLAN1, Core–router) with 10.10.10.1/29 sub network.

I need to put into router Ethernet interface an IP address secondary of the 172.16.X.X network, but I need to NAT from this IP address to a LAN IP address of VLAN2, 10.10.11.1/24.

IP address secondary: 172.16.1.1

I mean every request to 172.16.1.2 (Virtual IP address) the route must to NAT to 10.10.11.2.

It´s possible?, The IP address is not directly connected to router, it can reach this IP by one static route.

Thanks.
