In this video lecture, I am going to demonstrate to you step by step how to configure Site-to-Site VPN over an IPsec tunnel, which is the most secure and meets today's security standards, and then verify an IPSec Site-to-Site VPN tunnel using virtual tunnel interfaces.
These are 3 parts of the mastering video series.
1- Configured OpenVPN Site-to-Site VPN over a Peer-to-Peer (Shared Key)
2- Convert/ Transition existing Peer-to-Peer (Shared Key) to “Peer-to-Peer (SSL/TLS) VPN tunnel
3- Configure a Site-to-Site VPN over IPsec VPN Tunnel
We are using the latest pfSense 2.7.0 community edition and the same applies to pfSense Plus software.
Part-1 • pfSense 2.7.0 New! | O...
We have configured Site-to-Site VPN over a Peer-to-Peer (Shared Key) VPN tunnel, as this is deprecated due to refusal with today's security standard but you can still configure it with some technical congestions, in the future release of pfSense CE peer-to-peer shared key option will be removed finally.
Part-2 • pfSense 2.7.0 New! | C...
In this video, we are going to convert (transition) existing non-security standard Peer-to-Peer (Shared Key) VPN tunnel to a “Peer-to-Peer (SSL/TLS) VPN tunnel” which is recommended in all situations, and this is the most secure and meets today's security standard.
And then in the final.
Part-3 • pfSense 2.7.0 New! | C...
We will also see how to configure an “IPsec VPN Tunnel” and interconnect your offices. Since you cannot convert your existing “peer-to-peer Shared Key” and “peer-to-peer SSL/TLS VPN tunnels” to a new “IPsec VPN Tunnel” as this is a completely different configuration we will see in action and configure it from scratch.
Why Site-to-Site VPN?
Site-to-Site allows you to configure only gateways in remote subnets, and you do not need to configure the network nodes themselves. In simple terms, the Site-to-Site method connects two offices to a single network, and the Point-to-Site method connects remote employees to the office. In this video lecture, we will consider an example of connecting two existing networks - physical and virtual.
You can configure your Site-to-Site VPN over the Peer-to-Peer (Shared Key), Peer-to-Peer (SSL/TLS), and IPsec VPN Tunnel.
Please Note:
OpenVPN has deprecated the “Peer-to-Peer (Shared Key)” mode as it does not meet recent security standards. The shared key mode will be removed from future versions. So, you should convert any existing “Peer-to-Peer (Shared Key)” VPNs to SSL/TLS and avoid configuring any new “Shared Key” OpenVPN instances.
But in our later videos, we will see in action how to convert the existing peer-to-peer shared key into SSL/TLS and configure IPsec VPN Tunnel from scratch.
Setting up your pfSense network and satisfying all the prerequisites are fairly straightforward, If you really want to know how to install and configure the pfSense firewall in your network then watch my related video created earlier.
Please note: all the traffic should forward through the pfSense firewall in order to establish a successful routing.
In the local area network, all the Servers and Desktops should set the IP address of your pfSense Firewall in their individual LAN gateway.

really helpful material with detail explanations.
Glad it was helpful!
Thanks for sharing this,great presentation!
Glad you enjoyed it!
Exactly what I was looking for. Thanks!
Great to hear!
Excellent video. How do we configure if Both sites have ddns?
Glad to hear that, for dynamic IP, use ddns instead of IP address.
Hello, the tutoriel is great and very easy to understand, however mine is not working and i don't know the reason.
I don't know if the problem is related to the "Remote Gateway" on phase 1. Well i have a public ip that is linked to a domain name. They're both pingable. And pfsense is connected to the ISP router which has a local network like 192.168.10.0/24. So i'm a bit confused on what to use as remote Gateway (the public IP/the domain Name/the ISP local router address) ? And on both sites it's the same configuration
IPSec VPN uses UDP ports that are blocked by most of the ISPs, you have to make sure the ISP is not blocking UDP packets, also you can use Wireshark for source to destination traffic/ packet analysis.
I would suggest building your local test lab with the same configuration and checking the result, at least you should be confident with your configuration.
You could also verify IPSec ports are listening, run those commands share the result with me.
netstat -an | grep LISTEN
sockstat -l
@@itkb With the command executed only TCP ports are LISTENING. There is nothing going on for the UDP
@@itkb But what is your suggestion about the "Remote Gateway" ?
great job sir all the contents are very helpful for us thank you. I want some help i have an IPsec VPN from the client's office to our office i am using PFSN, and I don,t know what firewall the client is using but my IPsec is working properly, and can access the client site properly in my office.
now i want to do so that this client site can be accessible remotely on an employee's laptop out of office for this purpose I have configured the OpenVPN server and used openvpn client export ues this VPN. Everything control is working fine but i can't access my IPsec client site. I have also added a push route for the client site but still it is not working. what can I do to access the site?
Glad it helps
Works greate with one exception... DNS isn't configured. Things can be accessed via IP, but not by host/server name. What needs to be done to get that to work?
Happy to see that this video assisted you.
This is really more of a DNS question than an IPSec question.
But I would love to reply though.
You could do this several ways and it depends on what DNS server your machines are using.
I would not suggest to probably forward queries for the zone across the tunnel to the correct DNS server.
1- Rather I would suggest that name resolution should be managed by your/company's own internal DNS server.
2- All nodes/ devices should use respective internal DNS server IPs for managing remote name resolutions.
3- Create a separate DNS zone/PTR if remote DNS domain name suffixes are different, otherwise same DNS name suffix will be fine.
I am also using the same domain name suffix in all my remote branches with different LAN IP ranges.
Simply create a "DNS A" record with with associated remote IP address, and the rest DNS server will take care of this.
It should resolved now.
Hello, I tested your solution, and it's working great. I have a question regarding multiple clients' connection with IPsec. Can you create a How-to for various clients' connections to a central office so branch offices can see each other?
Glad it's working, sure in future i will.
