Trying to get the CLIENT OpenVPN setup in TrueNAS to connect to pfSense

#1

Has anyone gotten TrueNAS to connect to their pfSense OpenVPN Server?

I want to have the TrueNAS at my house, and be able to backup things from my office.

I’ve tried to setup the client for OpenVPN in TrueNAS, but I haven’t been able to figure it out.

All sorts of errors! I can connect to the VPN via my android phone, but TrueNAS isn’t connecting.

Thanks for any tutorials or video’s showing the process on the TrueNAS side.

I have not yet done any testing with it as I still prefer to setup site to site VPN’s at the firewall.

Thanks for the reply. I was tossing that idea around too, and I think it’s really the best thing to do in the long run.
I have this box setup as the main pfSense box, so I ordered a second for the remote location.

edit to add info about the above computer.
It is $169.99 after coupon right now.
Intel Celeron N3450 (4 cores @ 1.10GHz) Burst Frequency 2.20 GHz
6GB DDR4
128GB SSD
Dual LAN
Wifi-Adapter doesn’t work with pfSense, so I ordered a DW1707 (atho) from ebay for about $5
It has a fan, and the temp is currently 47 degrees according to pfSense

I added a USB NIC too from Amazon for about $13. No need, just for fun.

Thanks for all of the video’s that you post, very good tutorials.

I’ve found myself in the same situation as you. Trying to get an OpenVPN client setup on a TrueNAS box I’ve setup for an offsite backup.

I agree with Tom that I’d prefer to put a pfSense box at my family member’s home, set it as a DMZ host on their ISP provided router and then have my own tiny network of the pfsense firewall and the TrueNAS box. That’s a project for another day - for today I just needed to get OpenVPN setup as a client.

I was able to do it by setting up an OpenVPN server on my pfSense box using certificate authentication only. No user/password auth. Then I followed this guide from the TrueNAS Resources - TrueNAS and OpenVPN client configuration

Hope this is helpful for you!
