DNS Resolves in WAN but not LAN
« on: December 08, 2017, 11:51:11 pm »
Hello All,

I'm new to pfsense. I have installed pfsense in Workstation with 3 nics. Primary nic from local LAN connected to bridge network (10.109.246.220). 2nd NIC for internal LAN (192.168.100.1). 3rd nics for DMZ but I have not assigned yet. Out of the box set up with default firewall settings. The Windows VM in internal LAN receive the IP from pfsense. Able to ping pfsense and 8.8.8.8 but internet is not working. From pfsense shell able to resolve the public dns. But not from the internal LAN.

I googled and tried many things as suggested by others, but nothing helps. Several times reset to factory settings and started from scratch, no clue yet.

Please advise how to proceed further.

Thanks in advance
Vijay

1.) Have you created pass rules (Firewall->Rules) for port 53 destination traffic in your rules tabs for each interface (excluding WAN)?
2.) Have you configured your DNS Resolver to respond to DNS queries for each interface (excluding WAN)?
3.) Did you configure your DNS Resolver to select WAN as your Outgoing Network Interface?
4.) Did you assign your DNS servers in System->General Setup?

Hi

Thank you for your response. For all your questions, yes I did. Please refer the attached screenshots and point me the missing rule.

What are 10.107.1.110 and 10.112.166.138 and where are they located on your network relative to PFSense?

Those are the DNS server from local LAN.

When you say "local LAN" are you referring to the local LAN connected to your LAN interface of PFSsense? Or are these going to be on the other side of your PFsense box? (i.e accessible via the WAN interface)

You mentioned VM Windows machine. Have you tried disabling the host firewall?
