Site-to-Site Star VPN with dual-ISP

[CheckPointerXL]

Hello everyone,

My customer wanna deploy a site-to-site like this:

First ISP Link works, but when i switch to Second ISP Link, VPN goes down.

what i did is: 

- On FW at left side, i create a star community with the center and the remote satellite; i selected in link selection "Use probing. Redundancy mode: HA" and putting in the box the two public IPs

- On FW at right side, i did a star community with two satellite gateways, each one with one pubblic IP address

VPN works only with link ISP 1, any suggestion? MEP can helps? thank you
