Make Galaxy accept remote access

In order to make Galaxy access remote access, I have set up the following parts:

1.      Uncomment the following line in universe_wsgi.ini file which located in your home directory of galaxy, and change the ip address to 0.0.0.0
host = 0.0.0.0

2.      Edit the iptables at /etc/sysconfig/iptables and add the following line into this file, where port_num represent the port number of your galaxy listening port.

   A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport port_num -j ACCEPT

       3. Restart iptables: sudo /etc/init.d/iptables restart

4. restart you Galaxy
