WebJul 17, 2024 · Since the encapsulating packets exceed the network's MTU, fragmentation is required, putting additional load on the IPsec routers, and increasing the total overhead. Accordingly, you can decrease the MTU before entering the tunnel (for all nodes using the tunnel). That reserves space in the outer packets to accommodate the overhead without ...
