NAT through VPN

yves_s — Mon, 14 Jan 2019 08:21:22 GMT

Hi there,

With my GaiaR80, I have this scenario :

VPNremoteSite1 My site VPNremoteSite2

Object 172.24.1.2 <-----------> 10.1.30.0/24 <--------------> Object : 10.0.20.132

there are two site-to-site vpn between
- VPNremoteSite1 and My site

- VPNremoteSite2 and My site

Remotesite1 doesn't know the RemoteSite2 network

I would like to do a NAT on "my site" so that 172.24.1.2 can access 10.0.20.32

who can help me ?

Hello,

Have you tried to NAT the object 10.0.20.132 under 1 ip in your site, for example: 10.1.30.132. Then when client in Remote Site 1 tried to connect 10.0.20.132, the traffic flow will be as follow:

Original packet from Remote Site1: Src: 172.24.1.2/dst: 10.1.30.132 --(VPN S2S Site1 and Your Site) ---> Translated packet: src: 10.1.30.x/dst:10.0.20.132 ---(VPN S2S Your Site and Site2)

Best Regards,
