MTU (Maximum Transmission Unit)

MTU is the largest packet size on a link; VPN overhead can cause Fragmentation if MTU is mismatched. For business users, clear policy and least-privilege access reduce risk more than ‘always route everything everywhere.’ If you travel often, this term becomes especially important because airports, hotels, and cafes are common interception points. If you’re tuning for speed, test different protocols and nearby servers at the same time of day to account for congestion. VPN Surf and Elite VPN guidance aims to keep the concept actionable, not just theoretical.
