Fortigate 500 Update Their Switch

Does anyone have an idea as to how long something like this might still remain within End of Support Date (EOS) Can a customer update their switch if the switch is not under support The FortiGate firewall will be under support.

Anyhow EOL does not mean the device will stopp working then;) Plus as long as you have a valid FortiCare License for the device you will get support even though EOL.

Solution (LAN SUBNET) --- port1 (FortiGate) --- wan1 --- Internet Configuration 1) Create firewall address objects for the ip address of the client and the wan1 interface ip address.

Note:By using Local in policy we cannot block UDP 500 traffic from an ip address that is already defined as peer ip address in site to site VPN policy.

Verification Run the debug flow commands for the verification.

The FortiGate should be seen to drop the packets because of local in policy.

Sometimes, due to routing issues or other network issues, the communication link between a FortiGate unit and a VPN peer or client may go down.

Packets could be lost if the connection is left to time out on its own.

The FortiGate unit provides a mechanism called Dead Peer Detection (DPD), sometimes referred to as gateway detection or ping server, to prevent this situation and to re-establish IKE negotiations automatically before a connection times out: the active Phase 1 security associations are caught and renegotiated (rekeyed) before the Phase 1 encryption key expires.

The commands in this article will help to configure DPD (dead peer detection) on IPsec VPN.

Solution You can configure DPD per phase1-interface as follows (default settings are shown): config vpn ipsec phase1-interface edit set dpd disable on-idle on-demand set dpd-retryinterval 20 set dpd-retrycount 3 next end DPD: Disable: Disable Dead Peer Detection.

On-demand: Trigger Dead Peer Detection when IPsec traffic is sent but no reply is received from the peer.

DPD-RETRYINTERVAL: How long is the interval in seconds after which a DPD will be attempted again.

With the default settings, DPD will be attempted every 20 seconds, 3 times.

In total after one minute without DPD responses the tunnel will be turned down.

On a dial-up server, if a multitude of VPN connections are idle, the increased DPD exchange could negatively impact the performanceload of the ike process.

For this reason, an option is available in the CLI to send DPD passively in a mode called on-demand.

IKE will only send out DPDs if there are outgoing packets to send but no inbound packets had since been received.
