Hi, I have: intranet.xxxxxxxxxxx.com -> ip A zeus.xxxxxxxxxxx.com. -> ip A both are redirections made with iptables to make ip A (local) accessed by world wide. When someone tries to access zeus or intranet by the hostname the host machine running IIS knows which website the user is trying to access. my problem is: how to block intranet.xxxxxxxx.com to be accessed by worldwide if it has the same ip as zeus.xxxxxxx.com? can i block by hostnames instead of an ip address?? thanks
