Pfsense 2.02 Ispec VPN tunnels drops randomly,but when the raccon service is restarted all tunnels are back up.Here is my ipsec vpn configuration.Any fix on this issue? I have tried enabling and disabling "Prefer older IPsec SAs" and also tried disbaling and enbaling DPD but still no luck.I have to restart raccon daily to keep the tunnels alive.Is this a BUG?

That's likely the same cause as I described here: Pfsense 2.02 ipsec vpn tunnel goes down randomly

misconfigured "Server IP" on PPTP server.
