Title: OpenVPN Obfuscate
Post by: Taomyn on August 20, 2018, 10:33:09 am: Is there a way to set up OpenVPN obfuscate? I saw an old thread alluding that it's possible but no instructions anywhere.

Thanks, but I want to be running it all myself

Yes, it's my firewall, that's what I was asking to set it up on -sorry if that wasn't clear. I have a compatible client and a need to start using it. Could do it by creating an internal Obfsproxy server, but that just makes it more complex, not that it couldn't be done.

Ah ok thanks, care to recommend any documentation on setting this up or is it already in OPNsense somewhere?

Thanks again.

... simply add it to the Advanced Options for client and server.

Cheers,
