iptables

I have been having some trouble getting the NVBU client working with iptables enabled. With windows firewall this is pretty straight forward to allow the different NVBU services access through the firewall, but I don't think you can do this with iptables. I have tried opening ports 20031 - 20106 for both TCP and UDP. When I setup this rule I am able to see the client in client management and make the initial connections, but I am unable to see the properties of browse with the filesystem plugin. I have also tried setting these ports in the firewall tab of both server and client and setting the client to outside firewall. I have not been able to find a KB article regarding the specific ports needing to be opened to allow the client to function with iptables enables. If I disable iptables the client works immediately.
