Question : how to use port 80 in untangle

Hi experts,

would like to ask help. Here's the scenario.

I had 3 public IPs 203.x.x.1 , 203.x.x.2, 203.x.x.3
I use untangle as our gateway and 203.x.x.1 is assigned to untangle while  203.x.x.2 and 203.x.x.3 are also assigned as alias of the untangle.

My question is:
how can i use the port 80 each public IPs since the web gui of the untangle is using on it? Any configurations needed to set?Please advise.

thank you very much.
