Creating Rules for Firewalls
If you have a firewall running or if you are in a hosted system such as Rackspace or Amazon Web Services, you must add rules to the security group for TCP port 16902 and whichever command port must be opened in the firewall (such as 44223 for VW15 or 44103 for VH15).
If the operating system has a firewall running, you also must open the ports using the iptables command:
iptables -I INPUT -p tcp --dport 16902 --syn -j ACCEPT
service iptables save
If you are connecting to an Ingres II instance:
iptables -I INPUT -p tcp --dport 37455 --syn -j ACCEPT
service iptables save
If you are connecting to a Vector VW instance:
iptables -I INPUT -p tcp --dport 44223 --syn -j ACCEPT
service iptables save
If you are connecting to a VectorH VH instance:
iptables -I INPUT -p tcp --dport 44103 --syn -j ACCEPT
service iptables save
