How to Avoid VPN Blocks
Server switching
You can often bypass a VPN block by switching servers or going to a different VPN provider. The organization blocking your access may have focused on only the more popular VPNs when choosing what to block, so you may be able to gain access using a less popular service.
Obfuscated servers
An obfuscated server is able to hide the fact that a user is using a VPN. This makes an obfuscated server a good option if the list of banned servers is relatively comprehensive.
Dedicated IP addresses
With a dedicated IP address from a VPN provider, the address you use is far less likely to get blocked by an organization. Because it is only used by you, it is highly unlikely to pop up on a list of VPN IP addresses.
Change ports
When a network is blocking VPNs using a firewall that bans the use of certain ports, you can change the port you are using so your transmissions can still pass through. This requires discretion because if your methods are uncovered, admins may block each port you use to access VPNs, one by one.
Change security protocols

L2TP/IPsec
Layer 2 Tunneling Protocol (L2TP) is a method used to transmit internet traffic between users and machines, but it lacks adequate security. To resolve this issue, L2TP is sometimes used alongside Internet Protocol security (IPsec). IPsec encrypts the data packets being sent through the internet, making them extremely difficult to read, even by VPN blockers.
IKEv2
Internet Key Exchange version 2 (IKEv2) is a VPN protocol designed to work with IPsec. IKEv2 makes the encryption keys. This makes your VPN connection harder to block because the data cannot be deciphered without the secret key.
SSTP
Secure Sockets Tunneling Protocol (SSTP) is made to send and receive Point-to-Point Protocol (PPP) traffic. PPP is a protocol designed to send data packet-based traffic through the internet. SSTP uses a secure sockets layer/transport layer security (SSL/TLS) channel to send PPP traffic. SSL/TLS gives you security through the use of encryption while also checking how well the signal is going through.
PPTP
Point-to-Point Tunneling Protocol (PPTP) is used to overcome a free VPN blocker because it can transmit a lot of data quickly. This makes it easier to watch videos or listen to high-quality audio for PPTP users.
WireGuard
WireGuard protects data using encryption algorithms to help users bypass blockers. It can be used on a variety of different types of devices, including macOS, iOS, Android, BSD, and Windows.
Switch to Mobile Data
If you are on a network that is blocking VPNs, you can simply get off the network and use mobile data instead. This way, you do not have to interface with the blocking network at all. To do this, you will need a mobile internet service provider (ISP), which comes with a phone or mobile hotspot plan.
