I am trying to create a demo for a class of mine and I want to configure "fake" domain names on my laptop.
A previous question "Can I specify a port in an entry in my /etc/hosts on OS X?" contained an answer indicating that to do it you must use /etc/hosts plus changes to the iptables
"If OS X uses iptables you could point xyz.com to some ip in the hosts file like 188.8.131.52 and then:
sudo iptables -t nat -A OUTPUT -p tcp --dport 80 -d 184.108.40.206 -j DNAT --to-destination 127.0.0.1:3000
Since OS X doesn't use iptables, how do I do the equivalent using the tools available on OS X? (the original "asker" seemed to know how to do this, so it wasn't explained).
Thanks in advance.
