OPSense 25.1 changed the GUI for creating user certificate. Under Access >Users > click on the Cert Logo of whichever user you want to generate a certificate, then add a new one. Just make sure the issuer is the CA that you created. And the description is the same as user name

I followed your examples to the letter and they worked great. Thanks!

[BenUecker]

I really needed this! I couldn't find anything on the internet about the new way of setting of an openvpn server. thank you!

[erik_stein]

Thank you very much for this tutorial. Especially for explaining what some of the options mean and why to choose one thing over another. I struggled with several online guides to get my OpenVPN server working on OPNSense, but your tutorial got me up and running on the first try. 👍

[patrickdaxboeck]

Thank you for this video. This helped me setting up OpenVPN.

[fyphonsilter]

Hello, great tutorial and thank you for it. Everything works for me, but I cannot acess anything on the remote network via the VPN tunnel except the OPNSense firewall. Any ideas?

I can't get passed 13:44 when creating the server instance, My "OpenVPN Server" certificate keeps giving me a "Unable to locate a CA for this certificate." error, and it's a self signed one. I'm using version 25.1.7. So frustrating. Do I make a separate CA for my "OpenVPN Server" and sign it using that? Or can I sign it with the CA that we already created for the other user1 certificate?

edit: never mind, I missed the step where I was supposed to use the CA for the Server Cert anyway.

Thanks very much for the tutorial. From my legancy server I used to allow clients to login without client certificates. A client can login with username and password. How can I duplicate that fuction with the new server instance? Any help will be appreciated.

Hi, great Tutorial. Thank you!
Is it possible to see the other devices on the LAN when connected via VPN? My use case: Wake up a Device (Wake on LAN) in my LAN via Phone thats connected via VPN.

2/ my openvpn won't start :
The command '/usr/local/sbin/openvpn --config returned exit code '1', the output was 'Options error: error parsing --server parameters Use --help for more information.'


if u know how debug and get more information about the error

[roodeli]

hey, great tutorial. i did everything as in the tutorial, but when i want to do the client export i only see (none) exclude certificate from export. the created user is not displayed. i am using 25.1.1. do you have an idea what i am missing?

[karmakanic]

Thanks. Why do we end up with 2 Firewall rules (OpenVPN & OpenVPNServer)?

[dirkbernhard]

Mega tutorial but can you show in the next video with created rules or which rules you created or HaProxy or Nginx plugin with ACME CRT thank you

[Goatquietly]

Hi, great video thanks!

What is the purpose of Bind Address when setting up the instance? you left it blank?

And also where do you get the IPv4 number from?

Sorry complete noob here.

[RonaldCantrell]

Under Step 7, action 2, creating a rule to allow clients access to whatever IPs they intend to access, can you explain the need for IPv4+IPv6? I want to change the gateway from default to my WAN_ProtonVPN, but I get an error stating "You can not assign a gateway to a rule that applies to IPv4 and IPv6." If I change it to IPv4 only, I can change the Gateway, by when my remote client connects to OpenVPN, I lose connection to the local network and internet. Thoughts?

[Addyaddypot]

hi sir I have a multi user system running on my LAN (Server of the system is within the LAN) I wanted to access it also outside or OFFSITE, my ISP in my LAN is DHCP. Any Tutorials on this using OPNSENSE and OPNVPN? Thank you.

[merfild]

Thanks for the explanation. I am having one issue. When I export the file to my mobile, OpenVPN asks me about a "password", which password should I introduce, I don't remember introducing any password during the creation process, indeed, you also don't introduce any password in your mobile to create the tunnel. I would appreciate your help. Thanks ;)

[electricblue]

lol, another not so problem 😅 My OpenVPN server can be connected to from within my LAN/same WiFi.

[bangeek]

Great video, but this is only giving me access to my local network, not the internet. Did i mess something up?

[JB-tzpi]

Thanks. I must be doing something wrong. I keep getting TLS key negotiation failed to occur within 60 seconds. TLS handshake failed.
