/ip address
add interface=WAN address=X.X.173.97/28
add interface=WAN address=X.X.173.98/28
add interface=WAN address=X.X.173.109/28
/ip firewall nat
add chain=srcnat out-interface=WAN src-address=192.168.14.10 action=src-nat to-address=X.X.173.97
add chain=dstnat in-interface=WAN dst-address=X.X.173.97 action=dst-nat to-address=192.168.14.10
add chain=srcnat out-interface=WAN src-address=192.168.14.11 action=src-nat to-address=X.X.173.98
add chain=dstnat in-interface=WAN dst-address=X.X.173.98 action=dst-nat to-address=192.168.14.11
add chain=srcnat out-interface=WAN src-address=192.168.14.0/24 action=src-nat to-address=X.X.173.109

I just wonder If I replace this

add chain=srcnat out-interface=WAN src-address=192.168.14.0/24 action=src-nat to-address=X.X.173.109

with

add action=masquerade chain=srcnat out-interface=WAN

Which IP between X.X.173.97 and X.X.173.98 will be select to NAT

Thanks

If you make a masquerade rule, source address of packet change to preferred-src assigned by “/ip route” rules.
