Procedure
Step 1 Create a network object for the FTP server and configure static NAT with DNS modification. Because
this is a one-to-one translation, include the net-to-net option for NAT46.
hostname(config)# object network FTP_SERVER
hostname(config-network-object)# host 209.165.200.225
hostname(config-network-object)# nat (outside,inside) static 2001:DB8::D1A5:C8E1/128
net-to-net dns
Step 2 Create a network object for the DNS server and configure static NAT. Include the net-to-net option for
NAT46.
hostname(config)# object network DNS_SERVER
hostname(config-network-object)# host 209.165.201.15
hostname(config-network-object)# nat (outside,inside) static 2001:DB8::D1A5:C90F/128
net-to-net
Step 3 Configure an IPv4 PAT pool for translating the inside IPv6 network.
hostname(config)# object network IPv4_POOL
hostname(config-network-object)# range 203.0.113.1 203.0.113.254
