I have a client who has a Cisco ASA 5505 device. I am not familiar with these devices at all.
The client has a problem where it allows outbound from traffic from an old DNS server (10.236.72.100), but not from a new DNS server (10.236.72.3).
I currently have a forwarding setup on the new server to forward DNS queries to the old server.
Old server = Windows Server 2003 New server = Windows Server 2008 R2
As far as I can tell, the issue lies with the Cisco device. Can someone please help?
