daveo132 Posted March 14, 2021 Share Posted March 14, 2021 (edited) Hi, I've done some searching but not had much luck. I've recently moved over to PFsense and have had some issues with accessing my WebUI (Unraid) When I try to access it at the IP address I get an error: This site can’t be reached Check if there is a typo in xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.unraid.net. If spelling is correct, try running Windows Network Diagnostics. DNS_PROBE_FINISHED_NXDOMAIN This seemed to happen after I tried to set a static IP address for it in PfSense. Since then I've not been able to access it. I've removed the Static IP addition in the DHCP server and rebooted both my Unraid and Pfsense. Few other bits of details I can access my shares over the network. I have full internet access and can access my old router which I now use as a switch and WAP. (This has its DHCP server turned off.) I can access the UI at the machine itself, all appears in order. I've tried multiple browsers with no effect. I use an OpenVPN on pfsense (with its own DNS Server from NordVPN), I'm at a bit of a loss. Edited March 15, 2021 by daveo132 edited the custom adress Quote Link to comment
ChatNoir Posted March 14, 2021 Share Posted March 14, 2021 You might not want to post your remote access address on a public forum. I edited that for you. Quote Link to comment

daveo132 Posted March 14, 2021 Author Share Posted March 14, 2021 Even a reset to factory defaults of pfsense hasn't fixed it so I'm thinking it must be something on the Unraid machine itself. Quote Link to comment
ljm42 Posted March 15, 2021 Share Posted March 15, 2021 pfsense has DNS Rebinding on by default, that prevents you from getting a local IP address when you do a lookup on yourpersonalhash.unraid.net You need to disable DNS Rebinding in pfsense for the unraid.net domain. I don't have a lot of experience for this, but if you turn on help for the Settings -> Management Access page it says: pfSense: If you are using pfSense internal DNS resolver service, you can add these Custom Option lines: server: private-domain: "unraid.net" 2 Quote Link to comment
daveo132 Posted March 15, 2021 Author Share Posted March 15, 2021 ok that makes sense. I tried adding the domain in pfsense but it didn't seem to take. Disabling rebinding fixed the issue but that isn't a solution of course. Saying that, I did re-enable the dns rebinding and i could still access the page. Not sure if I was too quick to try accessing the page again or something else. I will keep playing with this throughout the day but at least I now know where the issue is! Thanks for the help Quote Link to comment
daveo132 Posted March 15, 2021 Author Share Posted March 15, 2021 that was it! I didn't quite realize where I needed to add that custom option but I go there in the end. Fingers crossed thats it now 1 Quote Link to comment

Just add a new line with the entry as @ljm42 suggested: 2 Quote Link to comment
simo241 Posted May 7, 2022 Share Posted May 7, 2022 hi, i add the entry in the Custom options however unraid is still not accessible, how can i solve? Quote Link to comment
Xylem59 Posted January 21, 2023 Share Posted January 21, 2023 same here... still open issue New Pfsense router box --> no access to unraid webUI... Quote Link to comment

Are you trying to use a legacy unraid.net certificate? If so, see: https://unraid.net/blog/ssl-certificate-update-2 Or are you having trouble with a myunraid.net certificate? You can follow these instructions to get access to the server while you work out how to disable DNS Rebinding on your router: https://wiki.unraid.net/My_Servers#How_to_access_your_server_when_DNS_is_down Quote Link to comment

You can follow these instructions to get access to the server while you work out how to disable DNS Rebinding on your router: https://wiki.unraid.net/My_Servers#How_to_access_your_server_when_DNS_is_down I ran unraid with my "old" router (Asus) with no issue. Today, I installed a new pfsense router on a new hardware, new box. Before I setup my new pfsense router, I set the unraid network.cfg file to keep my initial IP: Use_DHCP set to NO 192.168.59.xxx Now the new pfsense router is running (10.15.15.xxx) but I can no longer access unraid webUI using its IP. I have the below message: "The connection has timed out The server at 192.168.59.xxx is taking too long to respond." Any suggestion? Quote Link to comment

Your pfsense router is on a different IP network from Unraid, you don't want that. The easiest thing would be to give the pfsense router the same IP/network setup that the Asus had, using 192.168.59.xxx If you really want to switch over to the 10.15.15.xxx network, you need to let let Unraid get an IP on that network.

Thank you, i am pluging back my old router and will reset my pfsense accordingly. now I turned on my old router and my unraid IP has changed from 192.168.59.xxx to 169.254.53.xxx and cannot access the web... I am confused... Quote Link to comment
Xylem59 Posted January 22, 2023 Share Posted January 22, 2023 It seems that DHCP had some issue, found the resolution to force refresh DHCP, to run from the console directly: ifconfig br0 down && ifconfig br0 up Quote Link to comment
