What is the maximum transmission unit (MTU)? - SearchNetworking

WebIPsec alone shouldn't really have a problem with MTU. It's automatically calculated based on the egress interface MTU, actual PMTU (PMTUD must of course work on the path), and the IPsec encapsulation and crypto overhead. FortiGates also automatically apply TCP-MSS claming onto traffic passing through firewall policies into the tunnel. Web† The crypto interface VLAN MTU associated with the IPsec VPN SPA should be set to be equal or less than the egress interface MTU. † For GRE over IPsec, the IP MTU of the GRE tunnel interface should be set below the egress interface MTU by at least the overhead of IPsec encryption and the 24-byte GRE+IP header (20-byte
