Compute service node firewall requirements¶
Console connections for virtual machines, whether direct or through a
proxy, are received on ports
5999. The firewall on each
Compute service node must allow network traffic on these ports.
This procedure modifies the iptables firewall to allow incoming connections to the Compute services.
Configuring the service-node firewall
Log in to the server that hosts the Compute service, as root.
/etc/sysconfig/iptablesfile, to add an INPUT rule that allows TCP traffic on ports from
5999. Make sure the new rule appears before any INPUT rules that REJECT traffic:
-A INPUT -p tcp -m multiport --dports 5900:5999 -j ACCEPT
Save the changes to the
/etc/sysconfig/iptablesfile, and restart the
iptablesservice to pick up the changes:
$ service iptables restart
Repeat this process for each Compute service node.
