[resolved] Subsonic started but port not listen

Hi,

I installed a Subsonic server on my ReadyNAS Duo v2, started on port 4040. Until this morning I had it perfectly working in local, but not remotely. After many tries I think I eventually found the error (my mistake, in the config file). But meanwhile, I may have broken something else: Subsonic doesn't work anymore. At all.

Actually, the service well started:

root@Nas:~# ps aux | grep jav
root     11307  0.0  0.3   5276   760 pts/0    R+   13:06   0:00 grep jav
root     15605  7.5 60.8 402544 150264 ?       Sl   Oct22 101:54 java -Xmx150m -Dsubsonic.home=/var/subsonic -Dsubsonic.host=0.0.0.0 -Dsubsonic.port=4040 -Dsubsonic.httpsPort=0 -Dsubsonic.contextPath=/ -Dsubsonic.defaultMusicFolder=/var/music -Dsubsonic.defaultPodcastFolder=/var/music/Podcast -Dsubsonic.defaultPlaylistFolder=/var/playlists -Djava.awt.headless=true -verbose:gc -jar subsonic-booter-jar-with-dependencies.jar

but port is not in the LISTEN state:

root@Nas:/var/subsonic# netstat -an | grep 4040
root@Nas:/var/subsonic# 

and of course, Subsonic is not reachable, even with an SSH port forwarding, since port is not listen:

root@Nas:/var/subsonic# telnet localhost  4040
telnet: can't connect to remote host (127.0.0.1): Connection refused

Why can't I connect to this port?
Why service is well started but not using the port?

If it helps, this morning, when I was still a noob with iptables, I tried few experiments... but reboot is ok and I now have the following configuration back:

root@Nas:/var/subsonic# iptables -L
Chain INPUT (policy ACCEPT)
target     prot opt source               destination         
LeafNetsIN  all  --  anywhere             anywhere            
Chain FORWARD (policy ACCEPT)
target     prot opt source               destination         
Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination         
Chain LeafNetsIN (1 references)
target     prot opt source               destination

Thanks for helping!
