In some instances, you may need to manually find the MTU of you link first. TCP tunnels usually don’t require such adjustments. link-mtu. The maximum size of the final UDP packet after encapsulation minus the headers.

OpenVPN est donc un serveur VPN libre qui fonctionne en client et serveur. CÎté serveur, vous devez donc installer le programme et générer les certificats qui seront à installer sur le poste client.
