Pfsense and network DNS
-
@swampland7794 I unchecked that option after the screenshot was taken.

@swampland7794 well when you do your dns lookup now under diagnostics what do you see.. From your screenshot before that IP answered - but looks like it couldn't lookup google.. But showed a 0 ms response time..
Query something you know your local dns has a record for, or can lookup.. do a simple query to it with your fav tool other than pfsense for example..

seems unlikely that a new user would be doing that
True, but you never know, if you don't ask.
Take my wife for example. Give her a piece of tech and she pokes buttons "learning". then in a few days hands the device back to me, and says "it is broken, can you make it go". First question is always, "so what did you poke?".Maybe he setup some soft of pfblocker rules that are doing it?
not likely. Although there was a report a while back, that one of the "lists" had added 9.9.9.9 (in error) and anyone using that list, with that DNS suddenly didn't resolve.

@swampland7794 said in Pfsense and network DNS:
I have a mini server with technitium DNS server on it and I changed pfsense general settings to have this device as the only DNS server,
I noticed that all of my devices are using my DNS server except pfsense itself.
The IP address for DNS at 203.x.y.z doesn't seem like his local "have a mini server with technitium DNS server"
that address seems more like
inetnum: 203.128.32.0 - 203.128.63.255 netname: SawasNet descr: Beijing Sawas Technology Co.LTD. descr: Room 608,Beihang Boyan Building,No.238 Fouth descr: Northern Central Road,Haidian District,Beijing country: CN -
@johnpoz I chose Google and my docker server.
-
@jrey I manually set my subnet to something obscure like 203.128.45.0/24 which puts my pfsense box at 203.128.45.1 and my mini server at 203.128.45.2

randomly or do you own the address space?
-
@jrey randomly

ubnet to something obscure like 203.128.45.0/24
Yeah NOT a good idea at all, while technically you can do it - its a horrible idea to do that.. that space is owned by
inetnum: 203.128.32.0 - 203.128.63.255 netname: SawasNet descr: Beijing Sawas Technology Co.LTD.Whatever your doing your query to refused it.. You would have to look to the acl you have set on that NS your sending the queries too.
-
so what I said regarding ownership (good we agree) :

-
@jrey yeah its horrible practice to just pull public space out of thin air and use it locally.. You have all of rfc1918 to use, there is zero reason to use public space that you do not own.
-
@johnpoz oh that's bad. I changed it to 192.168.45.0/24. Thanks for telling me!
-
@swampland7794 I changed the DNS address to 1.1.1.1 and changed the subnet... I messed my home network and I don't have access. I'll fix it when I get home tonight and we'll see if that resolved my issue.
