FortiOS Release Notes

Changes in default behavior

Bug ID

Description

728468

Previously, all IPs in the IP pool and VIP were considered as local IPs if arp-reply was enabled. Because of this, the new NAT46/64 IP pool and VIP implementation could not use the arp-reply option, and a special route needed to be added on neighboring devices to route traffic to the FortiGate. Now, the IP pool and VIP have been removed from the local IP list, and the arp-reply option can be used for NAT46/64 IP pool and VIP (special routes on other devices are no longer required). This is an optimization of the kernel processing flow, without any command line changes on the user side.
