two web servers one public ip

hello. i have two windows servers 2003 hosting websites and RB493AH v4.0 with only one public ip. I need these website to be accessible from internet using different domains 123.com and abc.com. Is it possible to do this on mikrotik? I was trying to do this using this wiki: http://wiki.mikrotik.com/wiki/Multiple_Web_Servers, but it not working. P.S. I have hotspot enabled.

If these are important web-servers, perhaps it is better to move them, where is not HotSpot and public IP addresses available

But public ip is on wan port and masquraded. Hotspot is used only for our company pc’s with mac authentication for strict control. and even if i move these servers to network without hotspot the problem is same
