So airvpn has an option for me to change my protocol to SSL port 443 and they stated that the OpenVPN connection is no longer detected if deep packet inspection is used.

 

My question is how true is this? I've got some questions:

 

Does SSL port 443 provide true anonymity?

 

What's the different between connecting on TCP/UDP port 443 vs SSL 443?

 

If I do SSL port 443 is there really no way that my ISP can know I'm using a VPN at all and will just come across as normal HTTPS traffic?

Hi,

 

VPNs don't provide anonymity ever. Only TOR can do that.

 

SSL is generally slower because it encrypts your traffic twice but since some ISPs throttle or apply any kind of traffic management to VPN (or exotic) traffic it can be the fastest or only option.

 

Unless your ISP has a list of AirVPN's server IPs, your traffic will blend in with other people's and they won't know. Although having one HTTPS connection might look suspicious.

Your idea of VPNs is a bit wrong. Please read up on that.

 

What's the different between connecting on TCP/UDP port 443 vs SSL 443?

 

TCP/443 is used by HTTPS. Looking at IT networks around the world, it's less likely being filtered.

UDP/443 doesn't have this advantage, but OpenVPN usually performs better on UDP.

SSL/443 is essentially TCP/443 with a SSL layer on top of OpenVPN. The advantage is that clients looking at your connection between your computer and the VPN server (someone on your LAN, your ISP, etc.) will see a SSL connection if they analyze it. The downside is more encryption/decryption effort on your computer and the VPN server. Also, the overhead is bigger, leading to a small additional loss of throughput ("speed").

 

If I do SSL port 443 is there really no way that my ISP can know I'm using a VPN at all and will just come across as normal HTTPS traffic?

 

You can test it yourself. Use whoer.net or the WITCH script (currently a bit broken, though).


Always remember:
There's a guide to AirVPN,

Amazon IPs are not dangerous here,
running TOR exits is discouraged,

using spoilers for your logs is the proper way to heaven.
Same issues are rare! Search for solutions and if not successful open your own threads.

~ Furthermore, I propose that your paranoia is to be destroyed. ~
