I'm a newby and need some help crafting a new rule for my Cisco 3600 Router.
I have a number of dns server behind the router and until now this rule has been fine
! Allow return UDP DNS traffic to the DNS Servers.
permit udp any eq 53 host 184.108.40.206 eq 53
however I just put a new dns server behind the router that I wish to open to the world for dns lookups.
it's ip address is 220.127.116.11
how would I craft a rule to allow anyone into this ip address to do dns lookups?
thanks in advance.
