HEADS UP: OpenVPN deprecating shared key mode, requires TLS, deprecating cipher selection

Gertjan

Something isn't / wasn't working ?
"Shared keys" was already depreciated many moons ago.

So : setup a server (create a second ?!), and when done, redeploy the client "opvn" files to the OpeVN clients / users.

I use "Remote Access (SSL/TLS)", you could also chose for "Remote Access (SSL/TLS + User Auth).

@Gertjan thanks for the tips !

for the remote access VPN, if is SSL/TLS + User auth, does this working with freeradius as well ?

For site to site VPN with shared key, according this post: https://forum.netgate.com/topic/183644/site-to-site-with-shared-key-gateway-bug/3 there is no compatibility if server is V2.6 and client V2.7. Will the SSL/TLS tunnel will work between them ?? i have many 2.6 versions clients to upgrade.

I'm using FreeRadius myself for the captive portal.
Never tried to do this ...

You probably want also see this one also : FreeRadius on pfSense software for Two Factor Authentication although I presume that article was written for those who wanted to "why do things the easy way if much harder is so much better ?"

Keep in mind that 2.6.0 uses the "old" (now completly ditched because of security) OpenVPN (and now also old OpenSSL !!) libaries.
The recent pfSense uses the more modern OpenVPN and OpenSSL.

All this means that some options won't work anymore.
Some more options will work, but will be depreciated soon (as usual).
I Use OpenVPN myself, so I always have a look at the "source" : web pages like this and the classic openvpn support forum.

The OpenVPN client also changed to support the newer OpenVPN server.

And yes, I agree, syncing the entire openvpn user fleet can be a hassle.
