Issue with IPSec VPN on VSX Checkpoint (doesn't renegotiate)

[raquinog]

In the VSX Firewall (R80.20) I have configured two communities of IPSec VPN (star type) that I establish with remote branches in Cisco Routers (It use dynamic IP). The Central Gateway is the Checkpoint and the satellites are the branch office routers.

The problem I am presenting is that when the IPSec tunnel goes down, the tunnel is not restored again (automatically). The Work Around I execute is to generate a PING from the Checkpoint to the dynamic public IP of the remote branch.

I only present this behavior with a VPN community where I have branches with an Internet provider called Total Play here in Mexico.
The IPSec VPN tunnels from the other VPN community are with a different Internet provider and I have no problems with those.

I executed a tcpdump and Zdebug on the Checkpoint Firewall, and I see that if the communication arrives but the Checkpoint does not respond.

Any idea why I present this problem with the tunnels of this VPN community? since with the other I have no problems.
As mentioned I have to ping the remote public IP to reset the VPN tunnel.

use vpn debug to see what's wrong. It seems cisco side does not reply at all
