Seems to be working great as I can get individual statistics from the PiHole, and all clients can reach other clients using names instead of …
First, confirm the rules are active by issuing: Which, if all is well, should show our newly created rule 10. My pi-hole is configured fo use cloudfared, and at the wan out firewall I am blocking all dns requests except for the pi-hole.

It is privacy focused, w… I’ve followed your guide, added the PiHole’s IPv6 addresses to ipset and added the rules, replacing interface with “eth1” and the destination with the IPv6 of my PiHole. Conditional forwarding from pi-hole to dc.

This doesn't include a way for you to actually determine which devices respected the DNS server assigned in DHCP and which ones defied you, but I only care about proper attribution in the PiHole stats. You're going to have a bad time if you're relying on this to not break in a future update. You will need to apply a redirect on every VLAN for which you suspect “rogue” DNS configuration. My pihole is 192.168.9.3, and I wanted to redirect any traffic that goes out on port 53 back to the pihole Finding clients that are trying to bypass your rules can be done by enabling logging on those rules and then using something to parse the logs. Initially, I would not narrow this down, so allow all traffic of all types.
I set up a syslog container and configured the USG to send logs to that and then Telegraf to parse the logs and pump into my Influx and Grafana stack. Nice fault finding! In any case, good news is that now force redirection works for IPv6 on my network. I'll spare you the deep background on Masquerade NAT versus Destination NAT. Press question mark to learn the rest of the keyboard shortcuts. If you have setup the USG correctly, it will relay DNS requests to your pihole. I think you want the USG to be the default DNS for ALL zones. Make sure the address lines are correct, and that the inbound-interface lines refer to each of your target VLANs. At this point, you'll want to verify that PiHole is working, by manually overriding the DNS server on your test device and setting it to 10.10.10.10 or whatever other address you chose for the PiHole. Typically, a server VLAN will not have a possibility for rogue clients but rather be strictly configured, so I would not do it there (but configure DNS settings in the servers). If it’s untagged, then leave the “.#” off. We're going to use the latter, to capture all outbound DNS traffic and redirect it to the PiHole. There was one issue: ip6tables complained that “option –to-destination requires an argument”, but when I removed the square brackets, command was accepted. Use the “Routing & Firewall” – “Firewall” – “Groups” menu options for this: My group has 10 entries: 4x USG IP addresses, 1 per VLAN. It makes use of the scheduled task feature and is inspired on this community post over at Ubiquiti forums.
I think I get what you are saying basically for DNS needs outside USG should automatically use pinhole for that (once it’s all setup) and LAn needs it will not forward out but do so internally using the USG data. I handled this by setting my usg to point to pihole for dns, setting my clients to point to the usg. Pi-Hole is een stuk software dat je op een Raspberry Pi (hence the name Pi-Hole) kunt installeren. OK, This is quick and leaves a few bits up to the reader but here goes: PiHole set to use UDM as its upstream DNS server, UDM set to external DNS server of choice (I'm using 1.0.0.1 & 1.1.1.1), UDM set to give 192.168.0.2 as the DNS server to DHCP clients. Now capture all the commands you used in steps 1 through 3 and prepare them for use in a script. I therefore feel secure in flushing the rules before adding. There is a neat trick that we will use, and which makes it portable to another USG, makes it survive updates and provisions.
Remember the first four characters (and the last two, for good measure, to be able to positively identify the group name). Hopefully you now have a system that gives client names, etc. ._3-SW6hQX6gXK9G4FM74obr{display:inline-block;vertical-align:text-bottom;width:16px;height:16px;font-size:16px;line-height:16px} No dice. ._1x9diBHPBP-hL1JiwUwJ5J{font-size:14px;font-weight:500;line-height:18px;color:#ff585b;padding-left:3px;padding-right:24px}._2B0OHMLKb9TXNdd9g5Ere-,._1xKxnscCn2PjBiXhorZef4{height:16px;padding-right:4px;vertical-align:top}._1LLqoNXrOsaIkMtOuTBmO5{height:20px;padding-right:8px;vertical-align:bottom}.QB2Yrr8uihZVRhvwrKuMS{height:18px;padding-right:8px;vertical-align:top}._3w_KK8BUvCMkCPWZVsZQn0{font-size:14px;font-weight:500;line-height:18px;color:var(--newCommunityTheme-actionIcon)}._3w_KK8BUvCMkCPWZVsZQn0 ._1LLqoNXrOsaIkMtOuTBmO5,._3w_KK8BUvCMkCPWZVsZQn0 ._2B0OHMLKb9TXNdd9g5Ere-,._3w_KK8BUvCMkCPWZVsZQn0 ._1xKxnscCn2PjBiXhorZef4,._3w_KK8BUvCMkCPWZVsZQn0 .QB2Yrr8uihZVRhvwrKuMS{fill:var(--newCommunityTheme-actionIcon)} ( Log Out / In the EdgeMAX UI, look for the "NAT" sub-tab under the "Firewall/NAT" tab.

Now here is where it gets interesting.
Do I need to apply the redirect on the sub net that has my DNS servers AND the default VLAN? You could login to your pihole with SSH and simply PING one of your clients that now experiences time-outs. Okay, easy enough, there are guides for that too.
And because this article is about IPv6 redirection, we will revert to the use of the ip6tables command!
I really wish these NAT rules were configurable in the controller interface.
I recently setup Pi-Hole on my IoT network following the instructions on Scott Helme’s blog.
This should allow the return to correctly arrive.
The USG will apply destination NAT and redirect the request to PiHole, without changing the source. I will name my set of allowed DNS servers: IPv6DNS, as such: And then start adding addresses to this set (I will use my ISP’s DNS addresses for this): The use of the “-exist” predicate is there for the scripting case. > 2020-08-24 17:40 : 45K: 1-to-1-million-copy-. I don’t recall an option like that that’s why. Hopefully such a client will eventually fall back to regular DNS if it's trying to provide its main functionality. Please note the use of the ‘!’ – it stands for NOT. For a device to start making DNS-over-HTTPS queries, it first needs to find its way to an IP address willing to provide that service, generally by doing a normal DNS lookup for a server name.
My AD servers obviously maintain a DNS for my domain, and forward unresolvable queries to my PiHole. this also works really well for all devices on the network. Then, login to the SSH shell of the USG … Moreover, the query logs should show the actual clients that made the requests, not the USG.
If, for example, Chromecast and PiHole are on the same subnet, and Chromecast sends a DNS request to 8.8.8.8, the request will go to the USG (default gateway) to be routed out to the internet, and Chomecast will expect to see the response coming from 8.8.8.8. Later, you could decide to narrow it to the specific pihole address and or port number (53).
Change ), You are commenting using your Facebook account. I now only have to repeat these rules for all VLANs I want to have them active on. The people have awoken, ready to discover the most cringeworthy April Fools day “jokes” from the usual tech giants. My group has 10 entries: 4x USG IP addresses, 1 per VLAN.
This list tries to prevent that lookup from succeeding, but it's not 100% guaranteed like the firewall rules.
But I want to still have accurate PiHole logs about requests per client, without having it look like all the requests are coming from the USG. Please contact the moderators of this subreddit if you have any questions or concerns.
Need to redirect DNS Lookups from hardcoded devices on LAN that are effectively bypassing the local DNS server (PieHole 192.168.1.8).
