Maximum transmission unit - Wikipedia In computer networking, the maximum transmission unit (MTU) is the size of the largest protocol data unit (PDU) that can be communicated in a single network layer transaction. The MTU relates to, but is not identical to the maximum frame size that can be transported on the data link layer, e.g. Ethernet frame.. Larger MTU is associated with reduced overhead. Solved: MTU Optimization for Network Connect / Pulse NC/Pulse MTU size on the VA should be 100 less the total size of the MTU on the physical interface. This is due to the encryption and decryption of the packet. If you are seeing 1400 size out of the internal interface of the SA, then I would check to see what the MTU size on the client's VA is.
