Firepower NAT rules before and DNS doctoring

michael18

When I configure a NAT rule in 'NAT rules before' the option for DNS is not available, greyed out.

ive removed object names for ease of reading but NAT on CLI is roughly:

nat (inside,outside) source static 10.10.1.10 172.29.1.10 destination static 172.42.1.0 255.255.255.255 172.42.1.0 255.255.255.255 no-proxy-arp

im using FMC so config is via the FMC gui

its basically NAT A to B if going to C.

Is DNS only configurable in 1 to 1 nats (Auto NAT)
