internal DNS not working, setting DNS manually on host works.
Hi,
I am rather new to networking but will do my best to describe my problem.
I have a HW firewall running pfsense 2.4.2-RELEASE-p1. Wan is connected direct internet, and LAN to a switch distributing to 15 hosts on my home network. All hosts are effected.
The problem is that some addresses cant be resolved. For example www.google.se
If I with original settings try to ping google.se its not working.
C:\Users\christer>ping www.google.se Pinging www.google.se [172.217.21.131] with 32 bytes of data: Request timed out. Request timed out. Request timed out. Request timed out. Ping statistics for 172.217.21.131: Packets: Sent = 4, Received = 0, Lost = 4 (100% loss), C:\Users\christer>nslookup www.google.se Server: pfSense.localdomain Address: 192.168.1.1 Non-authoritative answer: Name: www.google.se Addresses: 2a00:1450:400f:809::2003 172.217.21.131 C:\Users\christer>If I in pfsense in System / General Setup set DNS Servers to 8.8.8.8, keep Gateway to none:
Still not working:

Any suggestion on how I could troubleshoot this or ideas what could cause this problem are most appreciated!
Best regards,
Christer Eriksson[SOLVED] Did a whole new installation of pfsense on my APU Alix box. Then just default setting and all works OK. No idea what caused previous installation to miss behave so badly.
