Dear: Roberto and Joseph.

as i wrote before, am using VPN site to site. 

Example:

Office 1: IP range: 10.1.1.0/24

Office 2 :IP range: 10.1.1.0/24

office 1  <--------Site to Site VPN IP sec  -----------> office 2

Hi I understood that and you need to use nat between the two sites, what security endpoint device are you using at each location ?

Just two routers.

[Roberto Kippins]

Hi bro this should also work for your routers just look at the cli config section.

Another option to consider might be L2TPv3.
