Had to change IP... can registered subsonic site IP change?

[akhliber]

Hello there, I have a registered subsonic.org site that can no longer be accessed outside of my home LAN... If one changes to a new IP and can't choose the old IP used to register the subsonic site originally as static address, is there a way to update my subsonic link to point to my new IP so that it can be accessed again?

Thanks!

Settings/Network

Save

Response may indicate that it could not authenticate it, but it should update the address at the subsonic.org server and give you access through servername.subsonic.org

If not you can still get there with Externatl ip:port# format.

Great, thanks! Your suggestion worked just fine, and access outside of the LAN is now working without a hitch. I appreciate your help!

Just had my modem replaced and got a new ip address as a result.

I tried out GJ51's suggestion but it gave me a timeout error.


Edit: I was doing some searching, (even though the forum seems really slow right now), and came across this thread. http://forum.subsonic.org/forum/viewtop ... ht=address

It's got to be my firewall, except I'm using Norton. Anyone know what I need to do in Norton?


Edit 2: I don't think the issue is with Firewall. I turned it off on Norton and still am getting the issue. I think the problem lies with Subsonic. I went to the tray icon and pulled up the subsonic settings to see if I can change the port. I tried changing the port but it would not save. It returned an error which said that access was denied.

I think the problem is that Subsonic is not able to save the new IP address internally.

Edit 3: Oops, I said I could access username.subsonic.org but I can't outside the network. I deleted that part out of my post.

I've tried everything. I can't get it to work.

Any help with this would be appreciated.

I have Norton 360 installed.

When you installed the new router, did you reset the port forwarding to the host PC?

Did you test with Canyouseeme.org to confirm that the port is open?

What do you mean "reset the port forwarding to the host PC?"

I have used canyouseeme.org. It is saying connection timed out.

Start with a fresh Java install to the latest version. If you have Java already, uninstall, then do a clean install of the latest version. If you use a 64 bit browser be sure to get both 32 & 64 bit Java.
http://www.java.com/en/download/manual.jsp If you have SS installed, uninstall it and delete the Subsonic directory (Windows).
Disable any DHCP services in any VOIP equipment or other additional routers you have. Only ONE router/device per network should handle DHCP assignments.

Most problems are due to improper setup on the router. Setting a fixed internal ip address for the server and proper port forwarding rules on the router are essential for long term stability.

First read: http://monroeworld.com/android/subsonic/ This is the Windows tutorial but most of the concepts apply to any setup. Specific setup instructions for other Operating Systems are available in the Tutorials section. http://forum.subsonic.org/forum/viewforum.php?f=6 and on the Subsonic website at http://www.subsonic.org/pages/installation.jsp

Never use port 80 (or 443 for ssl) - ISP's often use it or block it. 8080,8081, work fine. 808X Always works. I've seen others use different port numbers that have caused failure.

In Subsonic Settings/Network - UNCHECK " Automatically configure your router to allow incoming connections to Subsonic (using UPnP or NAT-PMP port forwarding)." Be sure to hit the SAVE button, you may have to scroll down to see it depending on your screen size. UPnP or Plug & Pray works sometimes, but not very often and you're better off learning what's going on anyway. You're dipping your toe into the network mgmt. thing anyway, might as well learn what's going on as home networks don't get simpler as time goes on. As your network gets more complex, you're going to have to learn this stuff! No time like the present.

The next step require you to READ your router's manual and understand how to do the following on your router. Every router is different and even routers from the same manufacturer can have very different looking administration pages.

Set up your router manually. uPNP might work, but most often it doesn't. Learing how to do it will be a skill you'll love having as your network grows.

Manually assign a fixed intenal IP and static route to your server at the upper end of the address range of the router, out of the way of DHCP, e.g. 192.168.1.254 Some router call this address reservation. I also set the settings on the network card of the host PC to use the same address I'm going to use on the router. This locks the connection at both ends.

Check the Subsonic Control Panel to make sure it's using the right port you're going to use. I typically use 8080, 8081, etc.

Set up port forwarding in your router to direct traffic on the selected port to your server. Consult your router documentation to do this, they are all a bit different.

Learn your external IP address assigned by your ISP. Go to http://www.canyouseeme.org/ enter your SS port number and click the Check box to be sure the Subsonic port is open.

Test your setup by entering your external IP:port# to see if it connects. e.g. http://108.17.27.224:8092/ If it works, you're good to go.

GJ51, I JUST figured it out...

I'm sorry to waste your time. Hopefully this will not all go to waste. I will try to describe what I did to fix it in case others come across this issue.

The problem lies with the NAT on the modem. Because the modem is intended to be both a modem and router it has NAT installed on it and will probably interfere with the NAT on your router. Here are the steps I took to fix it.

1 - Set the time capsule, which is the router I'm using, to bridge mode.
2 - Set up the port forwarding on the modem.
3 - Make sure the host PC is set up with the correct static address. In my case the static address the modem used was different from what the Time Capsule provided previously.

That's it! I have noticed that all of the instances where people come across a "Timed out error" is because they have two layers of NAT. Hopefully we can have this info included in an FAQ or Troubleshooting guide. There really are only 3 options for people in this scenario.

1 - Disable NAT on the Modem. Enable NAT on Router. Set up Port Forwarding on Router. (I couldn't figure out how to do that on my Modem.)
2 - Disable NAT on the Router. Enable NAT on Modem. Set up Port Forwarding on Modem. (The method I used)
3 - Set up Port Forwarding on both Modem and Router.

One thing to consider is security and performance. I don't know what the consequences of any of the above are regarding these. I would love to hear from someone about it. My modem has a firewall set, and I have Norton 360 installed on the host PC. Should I worry?

Good luck guys, and as always, thanks to GJ51 for all his efforts on this forum.
