Routing

Routing decides the path packets take; VPNs change your routing by sending traffic first to the VPN server. A practical tip is to verify behavior after OS updates, since networking defaults and DNS behavior can change unexpectedly. For business users, clear policy and least-privilege access reduce risk more than ‘always route everything everywhere.’ 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.
