assig public ip to some client

RouterOS General
1

hi dear
i have a mikrotik with these ethers:
ether1:192.168.100.1
ether2,3,4: DHCP-Client (providers gives me 10 Valid IP on each line)
also i have load balancing with fail over


can some of my client have public ip ?
1-client directly give Valid IP from provider
2-i map public ip (DHCP) to invalid ip
3-i map public ip (DHCP) to mac address

i know this command, but i dont have static ip to assign some clients
/ip firewall nat add chain=dstnat dst-address=10.5.8.200 action=dst-nat to-addresses=192.168.100.28
/ip firewall nat add chain=srcnat src-address=192.168.100.28 action=src-nat to-addresses=10.5.8.200

tank you so much

I think you should use scripting to see whether your IP address via DHCP has been changed and correct your mapping rules accordingly

could you please help me to write this script?
