I want to make it so if a user tries to use a different DNS server the request will be redirected to the one they should be using.
Looks like this might work:
ip access-list extended transparent_dns permit udp any any eq 53 route-map redirect_dns permit 10 match ip address transparent_dns set ip next-hop ip.of.your.server route-map redirect_dns permit 20 interface fax/x ip address xxx.xxx.xxx.xxx xxx.xxx.xxx.xxx ip policy route-map redirect_dns
I'm assuming this will work on the ASA. Any ideas on another way to do this or if this will even work?
