According to the wiki, on uses netmapping. However I have no experience with mutiple WANIPs from a single provider.
1:1 mapping
If you want to link Public IP subnet 11.11.11.0/24 to local one 2.2.2.0/24, you should use destination address translation and source address translation features with action=netmap.
/ip firewall nat add chain=dstnat dst-address=11.11.11.0/24 \
action=netmap to-addresses=2.2.2.0/24
/ip firewall nat add chain=srcnat src-address=2.2.2.0/24 \
action=netmap to-addresses=11.11.11.0/24
