Change MTU of tun
This tutorial lists the step to change the MTU size of a VPN tunnel
You can automate the setting of the mtu for the VPN port when the VPN goes up as suggested in script /etc/NetworkManager/dispatcher.d/01-ifupdown
. Scripts in the dispatcher.d
folder are called with the port and event as arguments.
So, create a script in folder dispatcher.d
with the following contents (if you want mtu 1200):
#!/bin/sh
#info : pre-up and pre-down are not implemented in network-manager
if [ "$2" = "vpn-up" ]; then
/sbin/ifconfig "$1" mtu 1200
fi
(The name of the script does not matter.) Then make it executable with chmod +x <script>
.
