# Create ACL 2000 to permit packets from network 4.4.4.0/24 where Host B resides (this step is
optional).

# Configure a 4to6 AFT policy for source address translation so that if the resolved IPv4 address
is in network 4.4.4.0/24, the address is translated into an IPv6 address by using DNS64 prefix
2000::/32 (this step is optional).
[Firewall] aft 4to6 acl number 2000 prefix-dns64 2000:: 32
NOTE:
It is optional to configure the 4to6 AFT policy for source address translation. If the policy is not
confi
g
ured, AFT uses the first confi
g
ured DNS64 prefix to translate the resolved IPv4 address into an
IPv6 address.
2. Configure Host A:
Perform the following configurations on Host A. (Details not shown.)
{ Configure IPv6 address 6::2/64.
{ Configure a static route to network 2000::/32 (the DNS64 prefix) and the next hop address
6::1.
{ Specify the IPv6 address (2000:0:303:305::, which is translated from 3.3.3.5) of the DNS
server.
3. Configure Host B:
Perform the following configurations on Host A: (Details not shown.)
{ Configure IPv4 address 4.4.4.2/24.
{ Configure a static route to network 6.6.6.0/24, which the AFT address pool belongs to, and the
next hop address 4.4.4.1.
NOTE:
Configure a static route to network 6.6.6.0/24 on the DNS server. The configuration procedure is
not shown.
Verifying the configuration
# Use the ping ipv6 hostc.com command on Host A. The ping operation is successful and the output
shows that the resolved address is 2000:0:404:402::. This address is translated from the IPv4 address
of Host B by using the DNS64 prefix.
# Use the display session table verbose command on Firewall to display the established sessions.
[Firewall] display session table verbose
