I have my network 10.0.30.0/24 in a vlan. DHCP is working and machines do have internet connectivity.

I want that network to use a specific IP address on ingress and egress

/ip address
add address=10.0.30.1/24 interface=RED_VLAN network=10.0.30.0
add address=[static ip 1]/29 interface=ether1 network=[static ip network]
add address=[static ip 2]/29 interface=ether1 network=[static ip network]

/ip firewall nat
add action=dst-nat chain=dstnat dst-address=[static ip 2] \
to-addresses=10.0.30.0/24
add action=src-nat chain=srcnat src-address=10.0.30.0/24 \
to-addresses=[static IP 2]

If I curl to whatismyip, it will not return the static address I assigned in the nat rules. It will only return [static ip 1]

I have tried assigning the to-address as individual endpoints as well to see if I could get it to use [static ip 2] to no avail.

Any ideas? What am I missing here?

Use netmap for consistency all around, see the example here:

e.g.

R1
/ip nat
add action=netmap chain=dstnat src-address=192.168.2.0/24 to-addresses=192.168.10.0/24
add action=netmap chain=srcnat dst-address=192.168.2.0/24 src-address=192.168.10.0/24 to-addresses=192.168.1.0/24

/ip route
add dst-address=192.168.2.0/24 gw=gw
