60d Fortigate

Reports of the VPN keep showing loads of errors with " 'Quick Mode Received Notification from Peer: invalid spi "
It's not every time, so with it being intermittent I have ensured both Sites have the same Encryption settings, and the Phase 1 and Phase 2 timers are definitely set to the same time/interval.
What else could be checked? Or what else do you guys who may have seen this before think it could be?
I don't have much more information at the moment, but I would like to arm myself with some potential solutions or scenarios to troubleshoot.
The suggestion most related to the error they're getting is to create a No-NAT rule. However in the VPN community in R80 you can opt to tick the option "Disable NAT within the VPN community" - Wouldn't this perform the same action?
Note: I've also suggested trying SHA256 instead of SHA1, and to not use PFS.
I have the same scenario, but in my case the vpn is established and when the user (behind the fortigate) try to access a server (behind the CP) the traffic is coming from the external interface and this traffic is dropped by antispoofing. I already configure a group to allow this network, but the traffic still coming from the external interface.
for example CP is expecting traffic from 10.0.0.0/8 to be coming from eth5 (internal interface), and now all of a sudden 10.100.0.0/24 is coming in via a VPN on the external interface
either eth5 is configured to broad for antispoofing or you need to configure exclusions on eth5
Assuming you've already verified the SA Lifetimes, ensure that the Fortigate is not using a data lifesize or tunnel idle timer. It sounds like the Fortigate is expiring the tunnel early for some reason. Also make sure DPD is disabled on the Fortigate unless you have explicitly enabled it on the Check Point side.
Also be aware that during Quick Mode Phase 2 negotiations the Fortigate is just like Juniper in that it is very picky about subnets/Proxy-IDs it will accept. The proposal must exactly match the subnets/Proxy-IDs configured on the Fortigate, unlike Cisco and Check Point it will refuse a proposal that is a subset of what is configured.

I have been trying to create a VPN with my SSG20 and Fortigate 60B, the problem is that i can only reach the untrust zone from both the sides. Below is the configuration i did on my SSG20. Any help would be useful.
Thanks for the reply ;-).I corrrected the outgoing interface. Now the juniper is showing the error "Phase 1 - Retransmission limit have been reached". Here i have checked the DH group. Selected the same encryption type, mode initiator is aggressive mode and also there is the same subnet for the proxy ID. But also thetunnel is not up yet...Please help.
So they are not able to reach other so check the pre-shared is matching at both ends or all your Phase I options at both ends like encryption algorithm or deffie hellman group for a mismatch.Check when you started getting the phase I messages.
Here the preshared key is matching, i have checked it many times. I am not allowing the internet at both ends and i am assigning a static IP address. Here i can hit the each others outgoing interface but not the private network. I have done VPN with Juniper at both ends and they are working fine but with fortigate 60B it is not showing a sign of connectivity.
First i tried with the main mode and again with the aggressive mode (both ends). Now i have again changed the setting to main mode. Its not working. I can only ping the remotes untrust interface. No more than that.
Thanks to all. I have a gud news. Now the VPN with fortigate is working. I canged the whole configuration and implemented a policy based VPN and also enabled a proxy ID. Major concerns are parameters so after many attempts finally the tunnel is UP and is working very fine. Thanks to WL, Gavrilo and all who help me in all possible ways.
A typical Fortinet Fortigate firewall appliance protects against known exploits, malware and malicious websites using continuous threat intelligence provided by FortiGuard Labs security services. It detects unknown attacks using dynamic analysis and provides automated mitigation to stop targeted attacks. It also provides industry-leading performance and protection for SSL encrypted traffic.
Health and Availability status : With real time or scheduled reports, you can view the history of firewall device performance monitoring and downtime statistics. OpManager also offers color coded data of when the device was Up, On Maintenance, Dependant unavailable, On hold, down, and not monitored.Ping device and traceroute options are very useful to IT admins.
Device summary and interface status: You can find all the devices connected to the firewall inthe device inventory. Interfaces connected to the firewall, their Tx traffic, Rx traffic, and uptime graphs are provided in the OpManager UI.
Other performance metrics: With OpManager's fortigate network monitoring, you can set various advanced availability, usage, and performance monitors for your Fortigate firewall network such as:
ManageEngine Firewall Analyzer is an OpManager's add-on forFortigate firewall monitoring which also functions as a stand alone tool for effective firewall log analysis. It helps to collect, analyze, and report firewall security and traffic logs. These reports help identify internal and external network threats.
OpManager performs Fortigate SNMP monitoring iusing the SNMP protocol. To obtain in-depth data about bandwidth and traffic management KPIs, you need flow technology. ManageEngine Netflow Analyzer is OpManager's Fortigate Bandwidth Monitor add-on which also functions as a stand alone tool for network bandwidth and network traffic analysis. NetFlow Analyzer leverages flow technologies to provide real time visibility into the network bandwidth performance and forensics of firewalls and all other network devices supporting flow technology.
OpManager, additionally, ensures the availability and optimum performance of your networks, servers, bandwidth, network device configurations, network security, IP addresses, and switch ports. This makes OpManager a holistic tool for all your IT Operations Management needs.
A firewall is a network safeguarding, surveillance and defense system that monitors and manages network traffic based on admin-defined security rules. Firewalls are undoubtedly the very essential line of defense for an organization's network. Statistically speaking, most hacks begin by knocking on the door, tinkering and tweaking up possible loopholes in firewall rules. An effective Fortigate monitoring software will set up your firewall security and monitor your system, looking for attacks and keeping your system up-to-date in a world where hackers are becoming increasingly more sophisticated.
