Network setup when more than one web site on same vdsl connection

[captainiom]

I am trying to design a network for our block of 20 apartments. The WAN supplies Ultima at up to 40 mb/s and the takeup on LAN is anticipated to be modest. However I have been told that two residents operate non commercial web sites currently on stand alone adsl with ddns. The netgear router supplied by the ISP obviously has port forwarding but how do I differentiate for traffic on port 80?? Surely I don't have to configure an in-block DNS
