Open a browser and head over to AirVPN.org. This is an area I’m currently evaluating and welcome feedback. These are important settings to reduce the chance of leaks in the event the VPN goes down for any reason. Select VL20_VPN tab and set the DHCP server as follows: Select VL30_CLRNET tab and set the DHCP server as below. Correct error in VL10_MGMT interface image Critically, we do not allow guests access to access any internal devices or subnets. VLAN Priority: 0 It’s possible to configure regular scrubs of these disks to ensure reliable long-term operation and email notifications should the ZFS array develop any health issues during use. Reset All States: Navigate to System > Advanced > Miscellaneous. If you haven’t got an AirVPN subscription, you can create an account here. We will create a list to define which ports administration traffic flows on, we will allow these ports with a dedicated rule on key interfaces later to ensure we don’t lock ourselves out when configuring the firewall. Security Your VL40_GUEST interface should look this this when done. Higher-level checksums are traditionally calculated by the protocol implementation and the completed packet is then handed over to the hardware. A managed switch is required to provide support for the VLANs. I also log any matches of this rule so I can see if any of my guests are attempting to access my local networks. Navigate back to Interfaces > Assign and configure the VL40_GUEST interface by clicking on the label next to the VL40_GUEST network port. If you see that the core which OpenVPN is running on is running at close to capacity, consider using a lighter cipher such as AES-128-GCM. Parent Interface: Your preferred parent interface Some sections might be outdated. persist-key: Don’t re-read key files across OpenVPN client restarts. To validate functionality run an extended leak test on each subnet. It is possible to setup multiple simultaneous connections to AirVPN which provides further redundancy and is covered in this guide. I know that pfSense will out of the box output to the console if it finds that an IP keeps switching MAC addresses but I think that's only if the DHCP server is on so it uses that feedback but, it would be nice to have something that would be able to do that for manually configured IPs and send an email or something. Your VL30_CLRNET interface should look this this when done. This assessment is influenced significantly by knowing that unencrypted queries are exposed only through my AirVPN endpoints therefore affording me anonymity. Updated destination field in DNS port forward Connect to each subnet in turn and verify a client receives an appropriate address from the associated DHCP pool. allow internal and external DNS resolution. I match the third octet of my IP address to the VLAN ID as this makes remembering which is which easier, so VLAN id 10 = 192.168.10.0, Click on the label next to ‘VLAN10_MGMT’, its likely to be ‘OPT1’ Heres the connection when connected to the VL20_VPN network where a 192.168.20.100 address has been awarded. With a nearby server I would look for a 15ms increase in ping times and a reduction in throughput of around 10% of the hardware capabilities. If the received checksum is wrong pfSense normally won’t see the packet, as the Ethernet hardware internally disguards the packet. Also verify you can’t access other systems and local devices you have connected to other subnets. The parameters relate to the following options, Navigate to Services > DNS Resolver > Advanced Settings. You will need to amend this alias as per your own networks requirements, but this should get you started. DON’T PANIC! Once you have completed your maintenance tasks, you need to re-enable the packet filters. You should see three rules created for the redirects for NTP and DNS. You will need to do this via the web console as you have no SSH access . Select next to begin. client: Specifies this is a client configuration. There was a chance that tagged traffic could be stripped of its tags and end up allocated to the parent interface introducing a security risk. To use AES-128-GCM you need to make some small changes to the OpenVPN configuration. As this is a fresh install, select Install. Firewall Maximum States: 1632000 (default), Firewall maximum table entries: 2000000 (increased from default), Cryptographic Hardware: AES-NI and BSD Crypto Device (aesni, cryptodev), Thermal Sensors: Intel Core CPU on-die thermal sensor, Servers: Your preferred Country or Single Server. We are going to create a few aliases which we will use in the creation of the firewall rules later. root@eve-ng:~/abc# unzip ArubaOS-CX_10_04_1000_ova.zip Archive: ArubaOS-CX_10_04_1000_ova.zip inflating: ArubaOS-CX_10_04_1000.ova extracting: ArubaOS … Major Revision for pfSense v2.4.5, 28 January 2018 Navigate back to Interfaces > Assign and configure the VL20_VPN interface by clicking on the label next to the VL20_VPN network port. A number of rules will be created automatically. We’ll now assign the OpenVPN interface we just created to a pfSense interface.
