Pfsense only OpenVPN Server with only single interface WAN
-
Ok!
Can you just point me in right direction for this, pfsense menu or …
i'm searching it since one Week and i'm bit confuse now…For set up transit network i'm need to create a new Gateway ?
Thx for you help !
-
No, you have to set up a separate network (VLAN) between your existing gateway and the pfSense vm. I don't know if that is possible on the gateway. If not you have to choose another option.
Give both devices an IP in that network.
On pfSense you have to deactivate the Outbound NAT.Than if the vpn is a site-to-site, add a static route to your default gateway on Google cloud for the remote LAN pointing to the new WAN address of pfSense. If it is a remote access vpn you have to set the route for the tunnel network.
BTW: If it is a site-to-site, the tunnel network mask has to be a /30.

Sorry but i'm very confuse… :-(
If I give you access to you on my PFSENSE WEB interface on Google cloud can you help me ?
-
I'm not familiar with Google cloud. Is there a virtual environment with an internet gateway, where you're able to add virtual network interfaces and internal networks?
If that is not possible take another solution.

I have only network card on my pfsense VM with google cloud.
Google cloud NAT public IP directly on private IP.
Can access to PFSENSE WEB with public IP and WAN IP in console is private IP
I install PFSENSE with this guide … https://blog.kylemanna.com/cloud/pfsense-on-google-cloud/
for other method can you explain more please ?

The crux of the matter is the gateway here for this solution. If you cannot configure it, that won't work.
So let's try the NAT solution.
That is assuming that all settings are like you wrote in your first post here.
For this one you have to enable the Outbound NAT in the pfSense web-GUI. Firewall > NAT > Outbound. Select the hybrid mode and save that.
Add a new rule:
Interface: WAN
Source: any
Destination: 10.142.xx.xx/20 (the Google Cloud local network)
Translation address: Interface addressThat should work if the vpn is configured correctly.

Thx it's work now ! :-)

Hello,
I'm new with pfsense, and for now I need it only because OpenVPN.I installed it to some cloud, also only with one interface for wan.
Because there is no possibility on that hosting to put few servers in the same vlan, I wan't to try with OpenVPN.Is it possible only with bridging? I googled so much these days, and found only this 6 years old guide
https://hardforum.com/threads/pfsense-2-0-1-openvpn-configuration-guide.1663797/
but it seems like it is obsolete.
Also in netgate documentation there is this link
https://www.netgate.com/docs/pfsense/vpn/openvpn/openvpn-bridging.html
which also not works because it is "irrelevant" for current pfsense version.Can you direct me how to make possible to put different cloud standalone servers to the same vlan?
-
There should exist smaller solutions for OpenVPN only.
You can get access by a transit network and routing if you have access to the default gateway, as already mentioned here. Or by adding a route to each remote device you want to reach or by NAT.
Also by bridging, in theory, but my experience tells me, that you will not get much support here for bridged openVPN, but you may try a new thread.
I can't help. -
Hi I am trying to do the same thing, could you share a screenshot of younnat config for this?
Thanks
-
Hello, I succeeded to setup on cloud with one WAN openvpn and connect devices from different places to one network.
ISP is Hetzner.
This is the configuration if someone need. Mostly done via Wizards, with small corrections afterwards.
Still need a little bit to harden firewall.

Hello again ! :-)
I'm setup PFSENSE (1 WAN nic) on google cloud with 6 pfsense (client) connected site-to-site, all client can PING my google cloud network 10.142.x.x/20
But when connect to my server on my google cloud 10.142.x.4 i'm can't PING my local network client ….
If i'm connect on pfsense GUI (server-side) 10.142.x.7 and make PING test on my internal local client 10.10.5.249 it's WORK !!!!
pfsense server 10.142.0.7
google cloud server 10.242.0.4pfsense client 10.10.5.1

6 site-to-site clients are connected to a single server? With CSO?

You have to tell the cloud server where to go to reach 10.10.5.249. Add a static route to it for the network of 10.10.5.249 and direct it to pfSense 10.142.0.7.

Hello,
All client can ping 10.142.0.x but FAIL from other side ….
When ping from 10.142.0.4 (Windows 2016) to any pfsense client it's fail :-(
If i'm log in pfsense server GUI 10.142.0.7 and test ping to 10.10.5.249 it's only work with OPENVPN interface if I choose WAN it's fail….
See images in this link for more informations …..

Where add static route in pfsense server or directly in google cloud interface ???
Because my Windows 2016 server VM on google (10.142.0.4) ogtain DHCP automatic and use 10.142.0.1 for Gateway. Can add route directly in my Windows 2016 ? do you have demo route for me ?
Thx!

Seems that the client is missing the route to your google cloud network.
-
What do you means ?
-
On the client you have to set the route to the 10.142.xx.xx/20 network.
In pfSense GUI enter the network into the "Remote network/s" box. -
on the client ?
client can ping google cloud VM
but
google cloud VM cannot ping client
-
Again the question:
All 6 site-to-site clients are connected to a single server? If yes, have you added CSO? -
Yes all 6 pfsense client is connected to same pfsense server (10.142.0.7)
CSO ?
