[SOLVED] DNS Resolver not working on last LAN added.

[Mnoya2]

Hi everyone,
I'm having some trouble with pfsense DNS Resolver. I added a new LAN to my pfsense network to configure it as a DMZ. However, for some reason, pfsense is ignoring or refusing my pings from the DMZ network... Some information you I may give:

1. I added a rule to allow any king of traffic.
2. DNS resolver has default configuration, I didn't change anything.
3. Pfsense is able to ping from its DMZ ip to any WAN ip.
4. DMZ machines are able to ping each other, so the communication issue is between any DMZ client with DMZ pfsense IP.
5. DMZ clients have a valid configuration (They are using the DMZ pfsense ip as gateway and DNS server).

@mnoya2

Have you allowed the DNS packets (TCP/UDP 53) on the pfSense DMZ interface ?
If not you should have seen packet blocks (deny's) , on the DMZ interface.

Do your PC's get ip via DHCP ?
Have you changed any of the defaults on the DMZ DHCP server page ??

Any protocol, any destination, no gateway?

Can you ping a DMZ device from pfSense?

Are the subnet masks correct on all involved devices?
