Recently I am mudding on a storage appliance named NexentaStor. NexentaStor is based on OpenSolaris and make use of ZFS implementation which looks pretty promising. It has a clean and easy to use GUI, hence it supports quite a lot of storage protocol like NFS, CIFS, ISCSI and even support Link aggregation on network layer too.
Everything is going smooth so far just one minor obstacles, that is its Web GUI by default listen on tcp port 2000. Basically tcp port 2000 is a valid port but somehow I am not able to access the Web GUI and the connection towards the port keep timing out from outside, though the port is working on the same subnet.
I started to suspect there is something to do with NAT and yeah it is. I put my NexentaStor server behind a Cisco ASA firewall with NAT enabled. However, it looks like the port 2000 traffic of NexentaStor overlapped with the Cisco SCCP (http://en.wikipedia.org/wiki/Skinny_Call_Control_Protocol) on port 2000 too. Eventually I have to change the port of the GUI to a non-2000 port.
Just an additional notes, to reconfigure NexentaStor Web GUI port, I have to get into the console and execute below command.
nmc@myhost:/$ setup appliance init
