"A virtual private network, or VPN, is an encrypted connection over the Internet from a device to a network. The encrypted connection helps ensure that sensitive data is safely transmitted. It prevents unauthorized people from eavesdropping on the traffic and allows the user to conduct work remotely."

Firewalla also has a built-in VPN Client which can be used to talk to many 3rd Party VPN Services.
What is Firewalla VPN Server?
Firewalla VPN Server places the VPN server inside your house. It runs inside of the little Firewalla box. This VPN service can only be used when you are outside of the house. You get the same level of security protection as if you are at home, provided by Firewalla.
Connect to Firewalla VPN = You are at Home
Easy to setup
- You don't need to open additional ports on your router.
- You don't need to manually port forwarding random ports from your router to your home devices.
- You don't need to learn complicated technology to bring up a VPN server.
- One connection allows you to access all home devices.
- Securely surf the internet with the benefit of Ad blocking, blocking porn sites and malicious sites.
- Securely access your home camera, NAS (network attached storage), smart door knob/power plug (IoT devices), and more.
- Your own private VPN server, not shared with others.
- Bypass censorship and internet filtering at work or another country.
- Prevent eavesdropping when you are on the road, at Starbucks.
Always at Home
- Take your video subscriptions anywhere. Stream Netflix, Hulu or any service just as you are at home. No restrictions.
- Access your banking / financial sites as if you are home.
- Bypass internet censorship or filtering when traveling to a foreign country.
- Free VPN Server runs inside your home network. There is no monthly fee or additional charge.
What This VPN Server is NOT
- This is not the traditional VPN service that you use to hide from your service provider.
- You can not use this service to bypass Netflix restrictions. (Unless you are traveling and have a Firewalla at 'home')
What does Firewalla VPN do?
Surf the web as if you are at home when you are not
Firewalla VPN Server allows you to easily set up an encrypted connection from anywhere in the world to your home. Although you are outside on public network, your security protection is the same as at home.
- You can access the internet as secure as you are at home.
- If you are at a place that controls internet access, you can use this to get around it.
- You don't need to open additional ports on your router when you are outside and want to view your home camera or file system.
If you are looking for VPN out from your home to a 3rd party VPN provider, please check out the VPN Client feature: https://help.firewalla.com/hc/en-us/articles/360023379953-VPN-Client-Beta-
Access your home network from anywhere
While Firewalla VPN allows you to safely connect back home, it can also allow you to easily access all your network-enabled home devices, such as IoT devices, NAS file system, etc.
The Firewalla VPN server is a transport service provided by security certificates. It is much more difficult to be attacked than an HTTP service provided by your camera. It also encrypts all traffic between you and your home network. Whatever sites you are surfing or files you are accessing are kept in private, and won't be snooped by anyone in-between.
VPN Server Configuration
Firewalla VPN server supports two types of VPN, please refer to the links below to see how each of them can be configured:
Testing VPN Server
Now you have everything set up. To test if your VPN is working, you need to test it outside of your own network, i.e. a network separate from the one Firewalla is installed on (many routers do not have this feature called NAT-hairpin which can allow you to VPN back to your own network). For example, if you are testing this on your phone with a VPN client installed, the best way is to switch it to cellular mode.
Still not able to connect to VPN?
If you still have problems, check the following:
Check 0: Wait a bit
- If you just installed Firewalla, it may take up to 1 hour to have the DDNS entry propagated. If you set up Firewalla VPN within 1 hour of the first power-up of the unit, please wait a bit.
Check 1: Running in Simple mode
If you have problems with port forwarding in simple mode, try this:
- Turn off global monitoring on Firewalla: https://help.firewalla.com/hc/en-us/articles/360008407613-Turn-on-off-Monitoring
- Reboot your router
- Try again and see if the VPN works.
- If works, turn back on global monitoring on Firewalla
Check 2: Do you have Public IP
1. Login to the router that the Firewalla is plugged in and look at the "WAN IP address" field.
2. Go to myip.com and compare that with (1)
If (1) and (2) are different, you don't have a public IP address. Call your ISP to get a public IP from them.
Check 3: Are you under double NAT
If you are under double NAT, that is, you have another router (second router) in front of the router (first router) that Firewalla is plugged into. If you have this configuration, you will need to do another port forwarding on the second router. Port forwarding the second router's public UDP 1194 port to the first router's 1194 port.
How do you know if you have double NAT?
First, look the physical connection of the router that Firewalla is plugged into. If this router is not given by the ISP, you may be under double NAT.
Next, check the following:
1. Login to the router that the Firewalla is plugged in and look at "WAN IP address" field.
2. go to myip.com and compare that with (1)
If (1) and (2) are different you are definitely under double NAT. In this case, please log in to the second router and manually setup port forwarding.
Check 4: Is your router running VPN
Some router may come with a default VPN server. If you want to use Firewalla VPN, please turn off your router VPN. Otherwise, the two VPN's will compete for 1194 port.
Check 5: If Firewalla is in DHCP mode, is your overlay network configured to be the same subnet as primary network?
In this case, VPN server may use the Firewalla's IP address in the overlay network to talk to VPN clients, instead of the IP address in primary network. When configuring port forwarding, you need to forward to the Firewalla's IP address in the overlay network. (You can check the IP address information in Settings -> Advanced -> Network Settings)
- If you use the VPN feature very often, we recommend that you do a static port mapping, because UPnP is not always reliable on certain routers.
- Firewalla Blue VPN profile may expire (depending on the revision of the software) around 30 days. If you encounter this issue, please just regenerate a new one. Go to VPN->setup->scroll to bottom, reset the profile and password.
- If you ever have needs to use port other than 1194, after you are done with port forwarding setup, don't forget to change your .ovpn profile (the line highlighted below):
remote xxx.d.yyy.com 1194
VPN Alarm & Notification
Once VPN is set up and enabled, Firewalla will send you an alarm every time a device is connected to your VPN Server. In case someone got hold of your profile and password, you are notified when they use your VPN service.
- If your router can reserve IP address for Firewalla, please do so. This will avoid problems if you have static port mapping.
- By default, Firewalla uses UPnP to map VPN ports, we have seen some routers are buggy, and may lose this port mapping to avoid this
- You can turn off and on VPN Server, this usually will fix the problem
- You should just add a static port mapping in your router if you use the VPN feature often.

- If you are using Firewalla Gold, you can manage the VPN Server Network in Network manager, and edit the VPN subnet if you want.
