Firewall rules between vlans

[Linuxfanboy]

I have PFsense configured for my firewall. I have a DNS and Mail Server on VLAN 1, a Web Server on VLAN 2, and my internal network on VLAN 3. I am trying to figure out how to configure Firewall rules to have my internal network use the DNS and Mail Server on VLAN 1 and have the DNS Server point to my Web Server on VLAN 1.

Any help would be appreciated.

Thank you
