Configuring pfSense. Make sure that pfSense is installed in VirtualBox. After completing the installation process, we can proceed with pfSense configuration. The steps to configuring pfSense are shown in the next section. Before that, let us make changes to VirtualBox network settings for our pfSense instance. PfSense is network firewall based on FreeBSD operating system with a custom kernel and includes free third-party packages for additional features. It provides same functionality or more of common commercial firewalls. Click here to learn How to Install Kali Linux in VirtualBox. Install pfSense in VirtualBox. Download pfSense from here.
OPNsense is an open source firewall distribution based on FreeBSD. Typical deployments are stateful perimeter firewalls, routers, wireless access points, DHCP and DNS servers, VPN endpoints, and UTM-machines. The OPNsense project is a fork of pfSense. VirtualBox Settings First of all we need to configure network interface on our VirtualBox.
Go to VirtualBox settings and open “Network” settings Here open a “Host-only Networks” and create a new adapter. Then open configuration of it, disable “DHCP server” and change an IP address to “10.0.0.1” Creation of a new Virtual Machine Now we ready to create a new instance of virtual machine. Tap on a New button in main window on VirtualBox. Here we need to input a proper name, select type and version. In next window we need to specify about of RAM OPNsense provide less requirements for a system resources and 512MB is more then enough.
Then we go to create of a hard drive Select “Create a virtual drive now” options. Then select hard drive file type For a first time, file type does not matter and we leave default value “VDI”. After that we must make a decision about storage on physical hard drive. For OPNsense recommend a “Fixed size” option. Finally we need to select location and size of the virtual hard drive. For this system is enough 2GB or more.
Tap a “Create” button and creation of Virtual Machine is over. Configuration of a Virtual Machine Now we have a new instance of virtual machine. Before configuration of it we need to download an installation image with OPNsense. We can find it on official site on. After upload an image we need to go into settings of previously created virtual machine and make some additional actions.
Firstly we obligated to select a “Network” menu item and enable a “Adapter 1” and “Adapter 2”. “Adapter 1” we attached to “Bridge adapter” and “Adapter 2” we attached to “Host-only Adapter”. Secondly we go to “Storage” menu item and need to configure a boot device. Here we must attach downloaded installation image to “Host drive” and assign “IDE Primary Master” to it. Then we assign “IDE Secondary Master” to “OPENSense.vdi”. Preparation is over and we ready to get to install a OPNsense. Installation of OPNsense The installation process of the OPNsense system is absolutely same as in pfSense.
This is normal because OPNsense is forked from pfSense. System configuration After reboot in the end of installation wizard, we wait a minute, until appear a console input for a login. Here login is root and password is opnsense. Now we see a system menu with options Let’s configure an interface.
Select the option number one. Skip VLANs configuration and go to WAN interface name. Set em0 as WAN interface. Then em1 as LAN interface. Base configuration of interface is over. Press the ENTER and confirm interface settings. After this action we see a initial system screen.
Below the welcome message we see a current configuration of interfaces. With WAN all right, but LAN needed additional configuration. Select the option number two in main menu. Type two for select LAN interface. Then input 10.0.0.1 as IPv4 address, 24 as subnet bit count and skip steps with upstream gateway address and IPv6. All describes steps you can find on screenshot below.
Moreover enable DHCP server for LAN, set 10.0.0.100-10.0.0.20 as range of clients IPv4 addresses and say yes in question about revert to HTTP as the webConfigurator protocol. You can find all this actions on the screenshot below too. Now we done base configuration of OPNsense as a firewall. We may test an internet connection using ping. Select the option with number seven on main menu and try to ping a default google-dns 8.8.8.8. We must see something like this: Sometime needed a reboot for successfully configuration of interfaces. If ping doesn’t work try to reboot the system.
Conclusion OPNsense has many benefits from his parent pfSense. This is lots of services and network monitoring functions, friendly web-gui, easy installation and configuration and so on. But this system has a primary orientation on usage as firewall. So it is good variant for installing on routers, firewalls and on home and production machines as virtual system for purpose of improve security.
Hi guys, Im new on the pfsense world. I've manage to setup pfsense in a VBox but cant lease IP to client PC connected to my lan(switch). HOST PC (with Vbox pfsense) Pfsense(bridge,Host-Only) -WAN (x.x.x.3) -em0 (x.x.x.4) -LanVirtual(192.168.1.2) -em1(192.168.1.1) This is the config, I can access the web gui so no problem but I cant network so i have to buy a 2nd NIC card.my built-in Lan is connected to a switch with my ISP, -my 2nd Lan is connected to a switch with my other clients pc. HOST PC (with Vbox pfsense) Pfsense(bridge,Host-Only) 2nd lan -WAN (x.x.x.3) -em0 (x.x.x.4) -192.168.1.3 -LanVirtual(192.168.1.2) -em1(192.168.1.1) what the heck i dont know what the config should be. Should I add a net adapter on my Vbox? It depends on if you already have said network in place, and are just adding the pfSense box, or if it's all greenfield.
If it's brownfield, I would configure the pfSense box in transparent bridged mode and just let it inspect traffic - no one will be the wiser unless something is triggered. If greenfield, then I would set DHCP on the pfSense to give out addresses on the 172.130.3.0/24 network, and in DHCP have itself advertised as the default gateway. If memory serves, pfSense will do dnsmasq as well, so it wouldn't hurt to let it do DNS as well. Give the inward facing interface an IP on your 192.168.3.0/24 network, and set a route on your internal network to point all 172.130.3.0/24 traffic to the IP of the pfSense box. That should really be all of you have to do, other than make sure the 172.130.3.0/24 network is permitted in NAT on the SonicWALL. Robert, It's fairly simple to do, basically you need to create a VIP on the WAN with the second IP (Use an IP Alias or Proxy ARP) and then switch the router in the Manual NAT mode and create a outbound NAT rule to NAT the traffic from your LAN out the VIP on the WAN interface.
When you flip the Router into Manual NAT mode, it will automatically create manual rules that match the existing 'automatic' rules. You should see the two default rules for the second LAN subnet, simply edit them and change the NAT Address from WAN Address to the Desired VIP. Here is a sample of what this would look like.
Note that this firewall is in an HA Pair - So I my LAN traffic goes out a CARP VIP and not the WAN IP. You'll notice that I've created a single set of rules to handle the entire site, rather than creating individual sets of NAT rules for each subnet, which is what pfSense will do when you switch to manual mode. (Though since you only have two subnets, probably not an issue, I have a lot.) But keep that if you add a another network, you'll need to create a set of outbound NAT rules for that network, OR, ensure your 'everything else' rule encompasses the new subnet. Also note that as with most things in pfSense, the order of your rules matters, which is why I can place the Wireless egress rules above the LAN rules, which the wireless network technically sits within. I am not sure how your virtualbox settings are but you should have both NICs added to the virtualbox VM. Next, in PFSense, you must make sure that the WAN interface is assigned to the MAC interface of your internal NIC on your PC. The LAN interface in PFSense should be assigned to the additional NIC that you added.
After you assign the interfaces correctly with the proper MAC addresses, make sure that the firewall on the LAN interface as an allow rule of any to any. Save and reboot PFSense. I also would suggest that you assign a different IP address schema to the PFsense LAN as to not get it confused with your PC's network, maybe something like 192.168.254.1 /24 After you reboot PFSense, I would get on your '2nd LAN' PC and statically assign an IP address in the range of your LAN interface on PFSense (such as 192.168.254.10 255.255.255.0). Then, try to ping the pfsense box on 192.168.254.1. If it succeeds, then you know there is correct connectivity and you can move to configuring DHCP. I hope this helps!
PFSense is a great platform and there are tons of articles online on configuring this. Let me know if you need additional help!
