Question : Block DNS resquests
Hi,
Is it possible to block DNS replies from my internal DNS server based on the ip address they contain using an access list on a 4506 cisco switch.
The idea is to make sure that if some one from outside runs a DNS that has a privivate IP addess, the switch will drop them.
Answer : Block DNS resquests
I think we need to change our DNS set up completly , so I am going to go away and redesign it from scratch. Other wise I will making a bad set up even more complicated.
