Create a destination NAT policy rule for static translation
that also rewrites the IPv4 address in a DNS response.
When you configure a destination NAT policy
rule that performs static translation of IPv4 addresses, you can
also enable DNS Rewrite so that the firewall rewrites the IPv4 address
in a DNS response based on the original destination IP address and
translated destination IP address configured for the rule. The firewall
performs NAT on the IPv4 address (the FQDN resolution) in a DNS
response (that matches the rule) before forwarding the response
to the client; thus, the client receives the appropriate address
to reach the destination service.
View the
DNS rewrite use
cases to understand DNS Rewrite and to help you determine
whether to specify that the rewrite occur in the
reverse or
forward direction.
You
cannot enable Bi-directional source address
translation in the same NAT rule where you enable DNS rewrite.
