Understanding VPN Blocking and Split Tunneling

Many websites and online services are increasingly blocking Virtual Private network (VPN) connections to protect against malicious activity,enforce licensing agreements,or prevent fraud. This can be frustrating for users who rely on VPNs for privacy or to access region-restricted content. This article explains why this happens and how to address it, specifically through a technique called split tunneling.

Why Websites Block VPNs

Websites employ various methods to detect and block VPN usage. These include:

• IP Address Blacklists: vpns use a limited number of IP addresses, which are often identified and blacklisted by websites.
• Port Blocking: Certain ports commonly used by VPN protocols can be blocked.
• Deep Packet Inspection (DPI): more elegant techniques analyze the content of network traffic to identify VPN protocols.
• geolocation Mismatch: Discrepancies between a user’s IP address location and their stated location can raise red flags.

The primary reasons for blocking VPNs are:

• Security: VPNs can be used to mask malicious activity, such as bot attacks, credential stuffing, and distributed denial-of-service (ddos) attacks.
• Content Licensing: Streaming services and other content providers frequently enough have licensing agreements that restrict access to specific regions. VPNs can be used to circumvent these restrictions.
• Fraud Prevention: VPNs can be used to hide a user’s true location, making it more difficult to detect and prevent fraudulent transactions.
