![]() ![]() On Firewalla Red, Blue, or Blue Plus, you can check the IP address information in Settings -> Advanced -> Network Settings. When configuring port forwarding, make sure you forward to Firewalla's IP address in the overlay network. Note: i f Firewalla is in DHCP mode, and your overlay network is configured to be the same subnet as the primary network, t he VPN server may use Firewalla's IP address in the overlay network to talk with VPN clients instead of the IP address in the primary network. On your box's main page, tap Network Manager, tap on the WAN connections, and write down each of their IP Addresses. If you have a dual-WAN setup, you may need to set up port forwarding on both of your upstream routers in order to make both WANs work properly. The number in the IP Address field is your box's IP Address. If you have a single WAN setup with Firewalla, tap on the gear button on the top right of your box's main page. Step 1: Get the IP Address of your Firewalla Box ![]() ![]() Tap on the link and follow the instructions to set it up. If it does, the app will display a "Need Manual Setup" link. On your VPN Server's Setup page, Firewalla will automatically detect whether port forwarding needs to be set up manually. The rest of these instructions is the same. If you have a double NAT setup and are looking for instructions on how to configure port forwarding on the second router, just replace the IP address of your Firewalla box in Step 2 with the IP address of your first router. Basically, you need to map your upstream router's public port to Firewalla's local port. In all other cases, you will need to manually set up port forwarding on your home router.īy default, Firewalla uses UDP port 1194 for OpenVPN, and 51820 for WireGuard VPN. If you're using OpenVPN, Firewalla's upstream router has UPnP enabled, and your box isn't in router mode, Firewalla will also automatically set up port forwarding for you via UPnP. If your Firewalla is running in router mode and has a public IP address, Firewalla will take care of everything for you– no need to take extra steps to set up port forwarding. this can also work with TCP but UDP is the better choice for a VPN.The Firewalla VPN Server requires its port to be accessible from outside your network. the important requirement is that the firewall router allow UDP "responses" for a longer period of time than OpenVPN retries to make that initial "connection". this ends up letting the two OpenVPNs to communicate with each other and establish your VPN. after your local end has sent a UDP datagram to the remote end, the firewall should let "a response" back in. each end will keep sending UDP datagrams to each other. if you know what your source (from) IP address is (easy to find out, google for "ip address") and you can configure a point-to-point VPN between your local computer and the remote host where the other OpenVPN is running, you may be able to make this work through your firewall without adding any port forwarding.Ĭonfigure both ends to communicate with each other on the same port. when a UDP datagram goes out via your firewall, it needs to allow the response to come back in, and to be sure it gets back to the sender. If you can do UDP communications to the whole world for many UDP port numbers, there may be a way around this and use UDP for OpenVPN as well (the better way to run OpenVPN). But you only need to do port forwarding of the OpenVPN connection itself, not all the connections to all the websites you might reach through your VPN. ![]()
