In this recipe, we will use the low-level ping
command to determine the optimal Maximum Transfer Unit (MTU) size for our OpenVPN setup. Finding the right MTU size can have a tremendous impact on performance, especially, when using satellite links, or even some cable/ADSL providers. Especially, broadband connections using the PPPoE (PPP over Ethernet) protocol often have a non-standard MTU size. In a regular LAN setup, it is hardly ever required to optimize the MTU size, as OpenVPN's default settings are close to optimal.
