I've used nearly all of them include the offering Simon mentioned.

I'm currently using this node...

On my Echo Dot I had to run the following as I didn't want to start Node-RED as root.  
It routes port 8980 to port 80.  
You need to enter 8980 as the port number in the amazon-alexa-hub

You need to run these commands on your Pi if your using a WiFi connection.

sudo apt-get install iptables-persistent  
sudo iptables -I INPUT 1 -p tcp --dport 80 -j ACCEPT  
sudo iptables -A PREROUTING -t nat -i wlan0 -p tcp --dport 80 -j REDIRECT --to-port 8980  
sudo netfilter-persistent save  
sudo netfilter-persistent reload

Or these commands if you're using Ethernet CAT cable

sudo apt-get install iptables-persistent  
sudo iptables -I INPUT 1 -p tcp --dport 80 -j ACCEPT  
sudo iptables -A PREROUTING -t nat -i eth0 -p tcp --dport 80 -j REDIRECT --to-port 8980  
sudo netfilter-persistent save  
sudo netfilter-persistent reload
