Multiple IP's on one card

is there a way to bind multiple ip addresses to one card, as in say to spoof sever ip adresses then forward them to the servers they are supposed to go to. I’ve already tried examples with the src-nat and dst-nat chains and they don’t seem to work on my network, any help would be appreciated.

You can always configure multiple IP addresses to single ethernet…

Should work fine. I am using it now. Just add the second address to the interface like you do the first.
/ip address add address=yy.yy.yy.yy/zz interface=ether1

In firewall filter nat, enter the dstnat route:
/ip firewall nat add chain=dstnat action=dst-nat dst-address=yy.yy.yy.yy to-addresses=192.168.0.4
This will route the public address yy.yy.yy.yy to the local server 192.168.0.4

sorry, Silly question, I figured it out right after I posted
