Yes this is a good idea. I dont know about how your hardware firewall is 
setup but I assume its port forwarding capable seeing as you have a web 
server behind it. If you have additional ports opened up this may allow 
someone to compromise a machine on the inside. From this machine the web 
server can be compromised. Its a good idea to slap on even a light 
firewall blocking unessecary traffic to the web server. Just as a 
precaution.
