The media MTU and PMTU values are stored in the IPv4sec Security Association (SA). The media MTU is based on the MTU of the outbound router interface and the PMTU is based on the minimum MTU seen on the path between the IPv4sec peers. Remember that IPv4sec encapsulates/encrypts the packet before it attempts to fragment it as shown in the image.
The Maximum Transmission Unit (MTU) is the size, in bytes, of the largest packet supported by a network layer protocol, including both headers and data. Network packets sent over a VPN tunnel are encrypted then encapsulated in an outer packet so they can be routed. Cloud VPN tunnels use IPsec and ESP for encryption and encapsulation. Because the encapsulated inner packet must itself fit within The MTU Size will be. 1492 Non-VPN traffic MTU Size - X IPSec Overhead. 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.

The campus VPN gives you a secure connection from your remote location to campus. A VPN connection is needed to do things like connect to a campus computer with remote desktop. The following links provide instructions on how to connect to the VPN based on operating system: If you need to access
Hi @cyerage From my understanding, virtual adapter's MTU size will be determined based on the MTU value set on the Internal Port of the VPN server (Configured-value 'minus' 100) and it will be pushed as one of the connection parameters.
Installation Instructions. Log in to vpn.mtu.edu with your Michigan Tech Account Name credentials using any web browser. Click Standalone VPN Client.; Run the installer from the downloaded locationand click Install to begin the installation.; After the installer is done running, click Finish.; Installation is complete and the BIG-IP EDGE Client will now appear in Start Menu > All Programs. Markiere 'MTU' und ändere den Wert auf '1300' (siehe unten) Klicke auf 'OK' und verlasse die Netzwerk-Einste llungen; CyberGhost VPN nutzt in der Regel einen Wert von '1.300', dies kann unter Umständen aber nicht der beste Wert im Zusammenspiel mit deinem Provider sein. See MTU Ping Test for information on determining the optimal MTU. Click Apply and restart the modem. WinPoET. When using WinPOET, the MTU registry setting is changed from the default of 1500 to 1492. After installation of WinPoET, if you have VPN, you will receive a message: "An MTU settings has been changed in your registry.
