Problem with UPNP and iptables

[pitit]

Hi,
I'm a new user on the forum and i have a problem to configur iptables to let pass the upnp connexions.
Is somebody have this problem?
All is working but not the upnp connexions.
The port 1900 is open.

I try to open port 4040 but it's not enough but with netstat i see that my server uses port 4040 and communicate on the pc distant with the ports between 63250 and 63255.

whithout firewall
tcp6 0 0 [::]:4040 [::]:* LISTEN 22632 810/java
tcp6 0 0 192.168.1.6:4040 192.168.1.3:63253 ESTABLISHED 1518346 810/java
tcp6 0 0 192.168.1.6:4040 192.168.1.3:63251 ESTABLISHED 1518341 810/java

with firewall
tcp6 0 0 [::]:4040 [::]:* LISTEN

this is all i find, and i know this is in IPV6

so I need help please

regards

Hi

nobody use iptables on subsonic server.
To be more precise, My server is used for web, ftp, and more services whose subsonic.
so i need use iptables (firewall) to used fail2ban to block somebody want to hack my server but when i want to use subsonic upnp, upnp is blocked by iptables.
but i don't find which port i used by subsonic to communicate with my phone or other material which see upnp media on my local network.

if someone known which port I need to open to have subsonic upnp, i thank him all lot.

If you need more détail (logs or other) ask me

Thank

regards
