Port Forwarding is not working quite right [SOLVED]

[dokjest]

Hi all and TIA for any help:

I am running Subsonic 4.7, and have setup on an Ubuntu 12.10 system and am registered with the domain of louvre.subsonic.org - I'm forwarding to an internal port of 15143 - when I enter the url for louvre.subsonic.org, the page cannot be found, and I note that the IP address on the address bar returns the proper external IP for my network but has the port appended to the IP - xx.xx.xx.xx:15143.

The actual IP is ninety-six, forty, one-sixty-nine, one-twenty-two. (I hate crawlers)

IF I strip the port off of the IP address in the address bar of my browser I reach the login page and am able to proceed normally. I had previously set the router to forward external port 80 to internal port 15143. I tested disabling this and that caused complete failure to reach the Subsonic server (As I would expect). Additionally I tested by disabling the port forwarding in Subsonic and trying to let the router handle this, but that did not help. I generally test with Firefox, but I get the same results with IE and Chrome. I've tested with multiple machines outside of my network and get the same results.

Here is the Java info if this helps: jetty-6.1.x, java 1.6.0_24, Linux (61.7 MB / 134.3 MB)

Since Subsonic IS running properly aside from the port/url issue, I have not included logs from Subsonic, but if you need other info, please let me know.

Thanks All!

Similar issues here with V4.6.
Depending on the type of setting created I get on <server>/subsonic either a 404:

Code: Select all

Not Found

The requested URL /login.view was not found on this server.


or a 503:

Code: Select all

Service Temporarily Unavailable
The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.
Apache/2.2.22 (Ubuntu) Server at 192.168.1.100 Port 80


For complenetess sake my setup:

Problem Description: Port forwarding to server extension does not work correctly (i.e. http://<server>:<port> redirect to http://<server>/subsonic)

for both of you :

I don't understand why you are using port 80 ? This is the port dedicated for http traffic, useful only if you host a web server.

For subsonic, the default port is 4040; if you want to use another one, you have to specify it in /etc/default/subsonic (Ubuntu/Debian) or /etc/sysconfig/subsonic (Fedora/RPM).

Then, you need to forward this port in your router configuration (so forward from external 4040 to internal 4040, with default config)

Finally, depending on your distro and personal configuration, you need to add an exception to your software firewall.

Thanks for the suggestion, I'll try tonight and let you know (Honestly, I would have to say I didn't think about not using port 80) So thanks and I'll post later.

for both of you :

I don't understand why you are using port 80 ? This is the port dedicated for http traffic, useful only if you host a web server.

Subsonic's frontend still is HTTP based. And I work in a corporate environment where only <10 ports are open for us to access to the outside, and some services (RDP / VNC / FTP) are already used on the machine running Subsonic. So that's why. Furthermore, some people use the service as well for demo videos of products that I really want to keep from the outside world to leak, so I want to provide an easy link instead of http://too.difficult:to/handle

For subsonic, the default port is 4040; if you want to use another one, you have to specify it in /etc/default/subsonic (Ubuntu/Debian) or /etc/sysconfig/subsonic (Fedora/RPM).

Done, default on machine is still 4040. I just want to reroute localhost:4040 to localhost/directory

Then, you need to forward this port in your router configuration (so forward from external 4040 to internal 4040, with default config)

Done, as intermediate solution (so currently another port is open but wrongly assigned so I can still use subsonic) the router is configured as <worldwide-ip>:<external-port> and connect that to <local-ip>:4040

Finally, depending on your distro and personal configuration, you need to add an exception to your software firewall.

As my router is my firewall, I've disabled ufw in ubuntu.

Don't get me wrong, your post is very helpful to check off all possible issues where it can go wrong. Thank you for that! However now I need someone like you who knows everything about apache2 and subsonic

*Solved* for me. Small iteration was to edit the configuration file for Subsonic in another way.

Solution in words:
Run and configure apache2
- Install apache2
- Install mod rewrite plugins for apache2
- Configure apache2 to reroute traffic from <ip>:<port> to <ip>/<directory>

Run and configure subsonic
- Install subsonic
- configure subsonic for working from another base directory

# For example, to specify that Subsonic should use port 80 (for http)

# SUBSONIC_ARGS="--port=80 --https-port=443 --max-memory=120"

# Reserve 1000 Mb for memory and define the context path for <ip>/subsonic to work

SUBSONIC_USER=root


Hope this helps!

Thanks everyone for your help - I am resolved. libussa, my problem was that I Was using a NAT and had the entry backwards (yeah - I know...DOH!)

Thanks again everyone!

dokjest - could you please set the topic title to [Solved] Port Forwarding is not working quite right?

Upgrade to 4.7 failed. Clean install to 4.7 was successful as are the settings defined this way.
4.7 clean install did not create a file in /etc/default named subsonic.

Creating a file named subsonic as /etc/default/subsonic with the content as above made everything work as desired.
Happy now!
