Site-to-Site Star VPN with dual-ISP

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

What is actually at the other end?
MEP and/or ISP Redundancy will likely be required here.

Hello PhoneBoy,

thanks for the reply. ISP Load Sharing Redundancy si already enabled. On both side we have two CP 1400 series.

anyway i had luck with the configuration described above; maybe something went wrong with pre-shared key.

hope my conf will help


thank you!
