Personally I use https://github.com/jpillora/chisel as a reverse Proxy through nginx, then connect through it using OpenVPN to bypass a similarly restrictive firewall. But this discussion is filled with other, similar hacks, I may have to try some of them.

I learned about chisel in PEN-200 / preparing for the OSCP.

Then I learned about, Ligolo-ng [1] which is a game-changer. I highly recommend checking it out. It is most applicable to a penetration test. It uses TLS so I'm not sure it could be used to address the issue mentioned in the article.
