[Swan] libreswan inside local network with NAT (left) - MacOS roadwarrior (right)

[Rodrigo Gruppelli]

Greetings!

I would like to know if it’s possible to achieve this kind of setup:

On the left side, there is my local network (192.168.0.0/24)

- The libreswan server is inside this network (IP 192.168.0.120) 
- The provider's router local IP is 192.168.0.1 and its external IP is valid but dynamic
- I use No-IP.org for dynamic DNS bindings
- I can tweak configuration inside provider’s router, to redirect external TCP/UDP ports to machines inside

On the right side, I’d like to be able to establish a tunnel with my local network, wherever I am in the world, using a macbook, acessing whatever machine inside my local network.

Is it possible to build a setup like this? What do I need to configure in ipsec.conf ? 

Cheers
Rodrigo
