Of immediate interest is the variable size of the payload section. The default size of this maximum transfer unit (MTU) is 1,500 bytes, but it can be increased to a maximum of 9,000 bytes under the rules of IP4. 7 Naively applying Eq. 2 would predict a sixfold decrease in packet count with a concomitant reduction in send times. Furthermore

Understanding MTU and MRU Configuration for PPP MX Series. PPP MTU and MRU for PPPoE Subscribers, PPP MTU and MRU for Tunneled Subscribers on LNS Linktropy WAN Emulator User's Guide Linktropy WAN Emulators emulate the bandwidth, delay, loss, and other properties of the wide area network link between two local networks. Depending on the model, the Linktropy product emulates either a single WAN link through one pair of Ethernet ports, or multiple WAN links through multiple pairs of Ethernet ports. Each link 1500 bytes over wan link of 1492 MTU. Is that possible Hi i have ppoe which allows 1492 bytes to pass through. This makes the mss go to 1452. I examined the packet and the IP header is 20 bytes the TCP header is 32 bytes and the data is 1448 which makes it in total 1500 bytes. Ive noticed that the tcp header is 32 beacause of a additonal 12 byte option Tunnel Overhead and MTU

Determine the MTU size of the LAN and WAN of a router

• MTU: Choose Auto to use the default MTU size, or choose Manual if you want to specify another size. • MTU Value: If you choose Manual, enter the custom MTU size in bytes. • Add VLAN Tag: Click Yes to support VLAN Tagging (802.1q) over the WAN port, or click No to disable it. • VLAN Tag ID: Specify the VLAN tag (ID) to the WAN port.

Configuring WAN Settings for Your Internet Connection

If you are using a Cable Modem WAN connection: 1500. If you are using a DSL WAN connection: 1492. Sample layout of the command: $> ping –f –l (this is a lowercase “L”) [MTU size] [destination] How to check your LAN connection of your router to your computer: $> ping –f –l 1500 How to check your WAN connection from your Set MTU in VPN environment in case of throughput issues X Definive MTU Size. EXAMPLE: 1492 Non-VPN traffic MTU Size - 73 IPSec Overhead 1419 Definive MTU Size. To set up the new MTU value, you can go under Network | Interfaces, select the WAN interface from which the VPN traffic is going through and: Navigate to Advanced tab. Change the MTU value with the one obtained with the previous test. Click OK. Configuring WAN Settings for Your Internet Connection
