The TCP connections will be "fooled" at the handshake to use a lower MTU. Please note that command is used to specify the MSS amount (for a MTU of 1300 the MSS is 1260). Cisco VPN Services Port Adapter Configuration Guide OL-16406-01 Chapter 5 Configuring IPsec VPN Fragmentation and MTU Understanding IPsec VPN Fragmentation and MTU Fragmentation in Different Modes The fragmentation process differs depending on the IPsec VPN mode and whether GRE or virtual tunnel interface (VTI) is used. Fragment non-VPN outbound packets larger than this Interface's MTU - Specifies all non-VPN outbound packets larger than this Interface's MTU be fragmented. Specifying the fragmenting of VPN outbound packets is set in the VPN | Advanced page. Ignore Don't Fragment (DF) Bit - Overrides DF bits in packets. Aber manchmal scheitert das VPN an eigentlich schon gelösten MTU Probleme. Gerade Menschen hinter einem DS Lite Anschluss und / oder Nutzer eines L2TP/IPSec VPN (im schlimmsten Fall eine Kombination aus beiden) bemerken ein seltsames Verhalten.

MTU problems may result in degraded network service, but may not affect some users’  When using VPN, there is additional overhead and you may need to reduce the MTU to I often set up vpn tunnels on different network devices(cisco, juniper) and one day I read an info about MTU: because of perfomance issues its better practise to reduce MTU size Maximum transmission unit (MTU) size for IPsec tunnels.

This article explains how to set the MTU value on the default WAN interface whenever the VPNs are experiencing throughput (or packet retransmission) issues. Configure your peer VPN gateway to use an MTU of no greater than 1460 bytes. We recommend a value of 1460 bytes because that matches the default MTU  Packet with 1500 bytes comes via Inside Eth interface where MTU is 1500. Case 1) no MTU limit set on VPN tunnel.
