    Changes with .dev domains in
mind.
Step 1 : Assign at least two IP address to your MAC OS (one per domain), let's say :
192.168.0.51
192.168.0.52

To setup the second IP you will have to add a second Ethernet Adapter (logical not physical).
Step 2 : As you don't have a DNS server, you could setup your /etc/hosts file, by adding :
192.168.0.51     dev.hostone.com
192.168.0.52     dev.hosttwo.com

Step 3 : Assign aliases to your loopback interface :
sudo ifconfig lo0 192.168.0.51 alias
sudo ifconfig lo0 192.168.0.52 alias

Create /etc/pf.anchors/dev, containing:
rdr pass inet proto tcp from any to 192.168.0.51 port 80 -> 127.0.0.1 port 8000
rdr pass inet proto tcp from any to 192.168.0.52 port 80 -> 127.0.0.1 port 3000


Edit /etc/pf.conf. After rdr-anchor "com.apple/*" insert rdr-anchor "dev"
(on its own line). After load anchor "com.apple" from "/etc/pf.anchors/com.apple" insert load anchor "dev" from "/etc/pf.anchors/dev" (again on its own line). It'll look something like this:
scrub-anchor "com.apple/*"
nat-anchor "com.apple/*"
rdr-anchor "com.apple/*"
rdr-anchor "dev"
dummynet-anchor "com.apple/*"
anchor "com.apple/*"
load anchor "com.apple" from "/etc/pf.anchors/com.apple"
load anchor "dev" from "/etc/pf.anchors/dev"

Test the config:
sudo pfctl -v -n -f /etc/pf.conf

Then reload:
sudo pfctl -ef /etc/pf.conf
