You can't.  OpenVPN is not https, so even if you use tcp/443, on a close
enough look it will be clear "this is not HTTPS".


How about using stunnel instead?


stunnel may be able to wrap your (TCP) traffic into TLS, whose 
unencrypted parts may look more or less like the TLS interwoven into 
HTTPS, but it still won't make your hours-long single-server VPN 
connection with keepalives and key renegs in regular intervals and 
carrying an SSH login with its single-keystroke upstream packets look 
like you browsed a couple websites.


Also, don't forget to configure the VPN server with --port-share, in 
case one of the nation-level censors you're trying to fool gets the idea 
of looking at your "interesting website" himself ...

So, use subnets within private address ranges (10.0.0.0/8, 172.16.0.0/12, 
192.168.0.0/16), or possibly
some other reserved addresses [1].

Do not use public addresses unless you own them.

> How can I make OpenVPN look like an HTTPS connection?

Do you mean to obfuscate OpenVPN traffic so that an attacker thinks it is legit 
web traffic?

I don't think OpenVPN does that: but you can run OpenVPN over TCP over tor, and 
use all
obfuscation methods that tor supports (obfs4, maybe even snowflake), some of 
them look
like HTTPS.

PS: please quote correctly (removing non pertaining text).

Hello,
Thanks.
I am testing this scenario in a virtual environment before moving it to the 
real world. For this reason, my server has two NICs. One that is directly 
connected to the Internet (enp0s3) and the other to the internal network 
(enp0s8).
What is problem?
How can I make OpenVPN look like an HTTPS connection?

Considering all the times Peter mentioned that "evade [nation-level] 
censors" is among his objectives, blackholing the clients' connections 
to Microsoft (auto)update servers while they're deep-diving might well 
be the *idea*. :-3
