This rule allows a device with the IP address of 192.168.10.10 on VLAN 10 to access any open service that is running on a device with the IP address of 192.168.20.10 that resides on VLAN 20: Option Value Action Pass Interface VLAN10 Protocol any Source 192.168.10.10 Source Port any Destination 192.168.20.10 Destination Port any Description Allow device to device access Allow any device on VLAN 10 to access any port of single device on VLAN 20 Many of these examples assume you have multiple local networks and you want to allow communication between devices in the different networks.īelow are some scenarios for creating firewall rules for your LAN/VLAN interface(s): Allow a single device on VLAN 10 to access any port of single device on VLAN 20 When you create a new VLAN or a network on another physical interface, access to all other networks are blocked by default since there are no firewall rules defined for the new network (besides hidden auto-generated ones required for DHCP to function, for instance). LAN/VLAN Rulesīy default, the LAN network in OPNsense has anti-lockout rules (to prevent you from locking yourself out of the web interface) and an “allow any” rule which allows access to all local and remote networks. You will see a list of interfaces in which you may add firewall rules. To add new firewall rules for your various network interfaces, go to the “Firewall > Rules” page. It also helps make the rules more readable since you do not have to remember that 192.168.10.10 is your laptop, PC, Raspberry Pi, etc. Aliases allow for multiple values and you can quickly change the values for several rules at the same time. If you plan to create several rules for a particular device or want to combine multiple IP/network addresses into a single rule, you may want to use aliases. It is worth noting that any IP addresses used in the examples could be substituted with aliases. I thought it would be a good idea to consolidate a variety of scenarios into a single how-to that could be used as a quick reference guide. This is especially true once you become more experienced and comfortable with writing rules. Lets keep this civil and on target.When looking up information on how to write firewall rules in OPNsense, you may be looking for specific examples on how to block or allow certain types of network traffic rather than how to write firewall rules in general. Is there anything out there for the RPi that I could leverage?Įdit: Please keep any 'parenting opinions' out of this question. They finish their home schooling / chores, I can now flick it back on. kids have commitments (home schooling, chores, etc), I wish to 'flick a switch' and YouTube is now blocked. if going to YouTube, deny.Īlso (which makes this really hard) is that I don't want to block YouTube 24x7. I was really hoping that I could use my RPI (which is doing nothing/not turned on/gathering dust) to be some middleware hardware device that could be used to intercept any traffics from a specific set of MAC's or static LAN IP's and. I could manually change the DNS settings of the 'parents' devices, but this too is a pain. Initially I was thinking of OpenDNS but that would block everything in this LAN. I'm trying to block Youtube on my various children's devices, but have it allowed/open on the parents devices.
