How do I make sure that only one public address can use a one-to-one static NAT?
I want to make sure that only 63.xx.xx.0 block can reach my two servers.
Will this work?
ip nat inside source static 172.18.75.12 65.xx.xx.2 route-map trusted
ip nat inside source static 172.18.75.13 65.xx.xx.3 route-map trusted
ip access-list extended secure
permit ip host 172.18.75.12 63.xx.xx.0 0.0.0.255
permit ip host 172.18.75.13 63.xx.xx.0 0.0.0.255
route-map trusted permit 10
match ip address secure
