“How to Unblock a VPN
VPN providers are aware that some ISPs/networks are blocking VPN traffic. That’s why they invented ‘Stealth’ VPN technology.
A stealth VPN can disguise/scramble your VPN traffic so it’s either not identifiable as VPN traffic, or even better — disguised as regular TLS encrypted web traffic.
Here are the two tried and true techniques to unblock your VPN service on almost any network:
Technique #1 – Run OpenVPN on port 443
Port 443 is the port commonly used by SSL/TLS encrypted web traffic. This is a standard internet encryption protocol that you use every time you access a website with sensitive account data, like your bank, credit card, or tax account.
Since OpenVPN already uses the SSL encryption library, simply by switching the port # to 443, it will easily slip through all but the most rigorous DPI firewalls.
How to use port 443
Most high-quality, paid VPN services will allow you to switch the port # (or have dedicated server locations that access port 443). If you need help setting it up, just contact tech support for you VPN provider.
Technique #2 – StealthVPN / Obfuscation
Even if you use port 443, most VPN protocols still have a data packet ‘header’ which is like a fingerprint that can potentially allow a firewall to recognize traffic as VPN traffic.
By using a VPN service that has Obuscation or ‘Stealth’ technology, your VPN connection can rewrite or obscure the packet headers (smudge the fingerprint) so it’s unrecognizable.
VPNs with stealth/obfuscation technology:
IPVanish (or read review)
Proxy.sh (or read review)
Torguard (or read review)
VyprVPN (or read review)
VPN.ac (or read review)
See our Stealth VPN Guide for a full list.
Advanced Obfuscation Techniques
If you really want maximum privacy and unblocking power, you can run your VPN through the tor network. On the upside, this makes your VPN virtually unblockable (and highly anonymous). The downside of using the Tor network is your VPN will now be routed through multiple encrypted proxy layers (of varying speed) so you’ll be lucky to get 5mbps using this method.
Configuring OpenVPN to access Tor via obfsproxy is rather complicated, but fortunately there are several VPN providers that have built vpn-over-Tor support into their service.
