NAT on SVI

[Vinayaka Raman]

I have 4 sites with overlapping address (192.168.1.x)/24 under VLAN 10 SVI and it is a secondary range.

They should be able to talk to primary range and other VLANs at the site without any restriction via inter vlan routing.,

This secondary subnet is not advertised over WAN.

SVI for VLAN 10 is created on the 3750 core switch.

We want a solution that would let this all devices in 192.168.x.x to talk to the HQ temporarily.

I think about NAT on SVI as a solution.

Do you have any other good recommendation?

Can we do nat on SVI using route-map on 3750? What kind of license or IOS version is required?

Hi,

You can't do any sort of NAT on a 3750 switch.

I can buy an additional device switch or router that would let me do NATing

I need the local conversation to happen without NAT and local to HQ conversation via NAT..

Can you help me giving some idea to buy a router or switch? and about the connection..?

We need a static one to one NATing..
