Internet on windows but not ubuntu bad pfsense configuration?
-
@stephenw10 Its not after you told me i should probably have the localhost as respond i remembered i had in the beginning in general information the localhost and then not anymore. So i've add it back with the dns server (good or wrong way idk) But ly query is a lot faster now.
But the option "Do not use the DNS Forwarder/DNS Resolver as a DNS server for the firewall " is not set in.
@Raffi_ I also tried it a second and third time, but no result. Or ... the same result.
-
If you are using DNS resolver with forwarding mode, the first option will be the local host by default. There is no need to enter it again under DNS Server Settings in the General setup tab.
Edit, something doesn't seem right with those 1ms query times. How would it go from 8 seconds to 1ms? I think this might be the DNS lookup GUI bug I've seen in the past.
Run those dig commands from pfSense instead.
Diagnostics/ Command Prompt
dig @172.20.0.253 google.com
dig @172.20.0.254 google.comI think those might give you the real results.

just an idea
it would be worthwhile to look at and compare these:Windows: https://docs.microsoft.com/en-us/previous-versions//cc977482(v=technet.10)?redirectedfrom=MSDN
Linux: /etc/resolv.conf
search domain.net
option timeout:1
nameserver 1.1.1.1
nameserver 2.2.2.2
nameserver 3.3.3.3or something like that

Interesting, well the two DNS servers seem to be responding better now. That could also be because they are caching.
How is Ubuntu getting its interface settings? Is it statically assigned in Ubuntu or is it set to automatic (DHCP)? There were no leases in your DHCP list.
-
I assigned static ip through /etc/netplan/01-network-manager-all.yaml
Everything seems good to me....
Edit, maybe an non relevant information, i can not ping the other vms in the dmz network. But my other vms can ping my ubuntu vm. Could it be something to do with routing ?

Try running a packet capture on the DMZ of pfSense.
Diagnostics/ Packet Capture
Select DMZ, then in Count enter a very high value such as 10000. You can enter 0 but don't forget to stop the capture manually otherwise it will run a continuous capture and it can become a problem.Download the capture data to wireshark and check for DNS info.
Dumb question, but have you tried to ping 8.8.8.8 from ubuntu? Does that work or is that failing as well?

Nope doesn't work because its blocked by the school.
I'll try the packet in a few minutes

ICMP is blocked or google DNS server specifically is blocked?
-
ICMP I guess. I can ping outside the network but not 8.8.8.8 or 8.8.4.4 I wont recieve any result wit this commands i began the ping on ubuntu and then on the windows machine who got internet:

Download the capture data to wireshark and check for DNS info.So apparently my ubuntu machine does not send any dns request :

That's not good. Is it even able to talk to pfSense at all? Can you ping pfSense (192.168.1.1) from Ubuntu?
-
Yup but not able to ping windows machine

It can't ping Windows because by default Windows does not respond to ping. That has to be manually enabled in Windows. It is responding to pfSense though. So at least there is some sign of life there.

Damn forgot to disable fw on this windows machine. >.<"
So apparently I don't know why, I suddenly have internet on my ubuntu machine.
I did not change anything i've reset my ubuntu vm twice to be sure and it seems to work. What the hell is going on here :o i think i'm losing my mind

lol don't touch it. You have a number of things which don't make sense. Like for instance the ping to pfSense is taking on average 600ms. In reality it should be more like 6ms. You have two extra zeros of delay. That's not good.
-
Haha i won't but hope it will work when i will need it ! :D
Apparently even this is fixed. :192.168.1.1 is my gateway to pfsense and 192.168.0.50 is pfsense ip..
I really hope it will stay working as i need it crossfingers
Many thanks for your help guys!

you don’t have to disable it all, just use this
netsh advfirewall firewall add rule name="ICMP Allow incoming V4 echo request" protocol=icmpv4:8,any dir=in action=allow
-
Oow Nice good to know !! I actually disabled the fw just for testing, after the test i would reanable the firewalls but very good to know for my other servers maybe !! Thank you !

you welcome
