Issues with DNS forward
-
I am running both DNS resolver and well as DNS forwarder. I have a VPN VLAN that makes use of the DNS resolver with no issues. My other VLANs make use of the DNS forwarder, and my issue is that when I attempt to ping a name or even an IP address, it fails. The strange thing if I download, wget or ssh a domain there is not problem, but pinging an address, it fails.
I have checked my rules, and I have ICMP rules on both the WAN interface as well as the interfaces that make use of the DNS forwarder. I have NAT set up correctly, and obviously DNS is resolving, but when it comes to allowing ping to work, it is failing.
Any ideas on what it missing?

After looking closely at my rules, I found that my source was set for an address as opposed to the network. One quick change and all was good in the Universe!
