Unifi client isolation without guest

I have some Unifi WAP's and created a guest network. My understanding was that guest networks on Unifi WAP's have client isolation enabled.

I connected to that network with my iPhone and took a look at what the WiFiman app would show. And on its Discovery menu it lists other clients on that network. Isn't client isolation supposed to prevent clients on that network from seeing or even knowing about each other?

In the wireless networks section make sure the box is checked that your guest network is well, a guest network. Then in the guest control settings you can enable client isolation there. Enabling the guest policy is supposed to isolate the guest devices from being able to ACCESS other devices, and when working properly, it does prevent ACCESS between devices I once had firmware vomit and allow access, in spite of the guest policy, and an updated firmware fixed it.

For example, Fing, will SEE the other devices both on the guest network and the LANbut will not be able to ping them or access any of their ports.

Hence they have an IP address in segment Guest control. Lan setting. First of all let you know that applying restrictions to your guests will let them still 'see' other hosts because these restrictions don't block ICMP protocol, but still they can't even ping other hosts neither access. You can easily set them up if you have a Unifi Security Gateway.

Question feed.Setting up a guest network at your place of business is a fundamental way to add value for visitors. You may notice that business routers have another feature called access point isolation.

Router manufacturers call access point isolation different things. Your file servers, endpoints, devices—everything on the LAN—cannot be accessed through a router or access point with AP isolation settings engaged.

The benefits are similar to a guest network in this regard.

Additionally, it prevents devices on a wireless network from communicating directly with one another. This prevents hackers from using public Wi-Fi to steal data from other users on the network. It also stops someone taking down the wireless network by flooding it with traffic.

ARP stands for Address Resolution Protocol, a method of networked communication that discovers the physical Ethernet address of a device by pinging it with an IP packet. The phony IP tricks the other device into exposing its physical MAC address, which makes its data and communications visible to the attacker.

Enabling AP isolation on your router protects against the attack by cutting off that type of communication. Using your router to create a guest network is another way to separate visitors using the Internet and your networked devices and equipment. Having two Wi-Fi networks lets you configure each to meet the bandwidth and accessibility needs of your guests, while protecting company data on the LAN and primary Wi-Fi connection. With guest network administration, you have granular controls to regulate use of a designated guest wireless network.

You might set up quality of service QoS restraints that caps the bandwidth available to them, or place time restrictions on how long someone can use it. If you want to cut off communication between endpoints, using AP isolation is best for securing a wireless network. Note that if you were to set up your office wireless without dedicating a guest SSID, turning on AP isolation would prevent your networked equipment from seeing each other.

Places that frequently have a lot of guest users on their wireless networks should consider a router or access point.

Anywhere the general public is offered Wi-Fi, AP isolation helps secure a wireless network against ARP spoofing and man-in-the-middle attacks. Top Posts.

Cancel reply.How do you configure the USG firewall? I tried adding firewall exceptions to a Guest network and never got it to work. Source: leave blank Destination: leave blank. Note At first glance, you might think that this rule would block communication within each subnet as well, for example blocking Now, what if you have one device on a VLAN that needs access to one device on the LAN, maybe a laptop that must send backups to a server?

This is helpful! Thanks for posting this. This opens my eyes to a better way of organizing my firewall rules for VLAN communication instead of a blanket block, or a blanket allow. I think I have a pretty good handle on the different settings in the firewall, except for the connection type.

I found a few places on the interwebs that helped me break it down, and understand it, but that took hours of research to piece it all together. It may help to describe this as well. New to using Unifi gear and this was my only issue thus far.

Thanks for this. I followed your guide and added a rule to allow all private IPs access my Airplay speaker. In step 3 of the article, I say to leave all States unchecked, which should mean allow all states.

This is because, in case of being compromised, the 1st. Effectively, by having this rule, it allows the attacker to subsequently compromise the entire system. BM, thanks for that perspective. I see the threat from rogue devices inside the network as greater than the threat from outside. This was a great straight-forward tutorial with perfect explanations of the steps. I followed a few other guides and was getting some weird unexplainable at least to me behavior when I tested it.

Information Security Stack Exchange is a question and answer site for information security professionals. It only takes a minute to sign up. Many SOHO routers these days support a feature called "wireless client isolation", or similar. What this is supposed to do, in principle, is to limit the connectivity between wireless clients connected to the AP. Wireless clients can talk to the LAN, and reach the Internet if such connection is available, but they cannot communicate with one another.

How is this achieved? Are there any particular weaknesses which would allow this to be easily bypassed? The implementation that I've seen of this is done by fiddling with the MAC forwarding table on the access point.

Since the access point simply acts as a network bridge, it is fairly well suited to this kind of task. At the switching layer it is already collecting all of the heard sometimes called learned MACs and which interface it can be found on. Because of the way network bridges work I see this being fairly difficult to trick the access point into forwarding a packet to a client in spite of the isolation. Your best bet would be to attempt to talk directly to the other client, as if you were operating with an ad-hoc network.

When you send data to the AP it's encrypted with your unicast key. The AP then decrypts this and uses the broadcast GTK to send the data to the next system on the wireless network.

Because everyone establishes a unique unicast key to send data with you will no longer be able to see eachothers data. Bypassing this takes a little more effort and understanding.


If the clients system is fooled into using the GTK to send data it can now be seen and you will bypass the client isolation. Thus, if you set your local static ARP entry using the clients ip with a bradcast mac your local system will think its sending broadcast traffic when talking to that client and use the GTK allowing the client to see your traffic. I acknowledge that some advanced APs have arp control and layer 2 isolation where advanced tactics are needed but we're not talking about those guys were talking about your SOHO.

Wireless client isolation - how does it work, and can it be bypassed?The thing that sits in the corner and controls the color of your lightbulbs, do not need to have access to the same network as your other data. This makes sense, as once they are configured all they do is communicate out to their respective cloud services — and the management apps for them connect to that service, not directly to the device itself.

This also makes sense, since these devices are supposed to receive data from your your other devices - directly. My primarily use case for them is Spotify Connect so I can stream music to my stereo setups I have an old analog NAD receiver with some nice Dali speakers that do not have digital connections at allso being able to actually stream music to them is rather useful.

Note: The following information was correct at the time of posting, based on a setup with 1 x UniFi Security Gateway 3P 4. Once you have this network in place, be it either via WiFi or via physical VLAN tagging on a switch port or bothyou can start moving your devices over.

These devices then got a new IP assigned to them from the new network definition, and their management apps still worked without problems. In short, this means that connections that are already in place, or related to those established connections will be allowed. Give the rule a name that makes sense, enable it and expand Advanced.
