1. As the root user or as a user with sudo permissions, log on to the computer that contains the solution installer node .
2. Back up your existing firewall settings by typing the following command: . /etc/init.d/iptables save
3. On the computer that contains the solution installer node, add rules for the ports that are required by the installer by typing the following commands:

   iptables -I INPUT -p tcp --dport 8080 -j ACCEPT 
   iptables -I OUTPUT -p tcp --sport 8080 -m state --state 
   RELATED,ESTABLISHED -j ACCEPT

   iptables -I INPUT -p tcp --dport 443 -j ACCEPT
   iptables -I OUTPUT -p tcp --sport 443 -m state --state
