From any device on the network, check whatismyipaddress.com to ensure traffic is routed via the VPN.

Notes:

Routers can complicate DNS handling; consider configuring DNS to a private or Google DNS/Cloudflare to avoid leaks.

Advanced options and optimization

UDP vs TCP: UDP generally offers better speed; TCP can be more reliable in networks with strict interference or firewalls.
MTU settings: Start with 1500 and adjust downward if you see packet fragmentation issues; sometimes 1460 or 1420 helps.
DNS configuration: Use a trusted DNS provider e.g., Cloudflare 1.1.1.1 to avoid DNS leaks; ensure DNS requests route through VPN when connected.
Kill switch: Always enable Network Lock when privacy is a priority, especially on Windows and Android.
Split tunneling: If you only want specific apps to go through VPN, use split tunneling where supported to improve speed and reduce unnecessary VPN traffic.
Automatic reconnect: Enable auto-reconnect to prevent accidental exposure when the VPN drops.
DNS leak tests: After connecting, run a DNS leak test to confirm queries are not leaking outside the VPN tunnel.
