Help with port forwarding

[atrdriver]

I'm trying to figure out why my owncloud server stopped working from remote access. I can still access it from inside my network, but not outside. It was working some months ago, but has since stopped. I have my ASUS router set to forward port 58001 to 443 on the servers internal IP address. I use no-ip.com as a DDNS solution. At first I thought maybe they weren't redirecting to my public IP address, but I have also attempted to access it using the actual IP address and can't.

If it's germane, I am running the owncloud on a Ubunto server setup.


I looked for a tool online to test the port forwarding, and found this website:

Link Removed. Clicking on it might endanger some people. (JackMDS, Moderator).

When I type in port 58001 it reports that it is closed. I then attempted to set 59001 to redirect, and when it type 59001 it says it is closed as well. Shouldn't this tool report the port as open since I have it set up for port forwarding in the ASUS setup?

Thanks

Use this site to check your ports. https://www.grc.com/x/ne.dll?bh0bkyd2

It could have something to do with your cloud. In my case I have a built in SSH server in the router flashed to DD-WRT and I couldn't remote in and I have the same DNS service. It turned out to be that I had to enable remote access.

So you might have to configure something in the software.

Are you using updated firmware for the router?

I'm not sure what that site was supposed to tell me. It said that the equipment at the target address did not respond. It said nothing about open ports.

I had this working in the past, and to access the owncloud server remotely I would have to go to:

https://ip.ad.dr.es.s:58001/owncloud

So I had the router set up to forward port 58001 to the ip address of the ubuntu server on port 443. Again, I can access it all day long from inside my network, so I know the server itself is working. Just for some reason the router doesn't seem to be forwarding the port requests and I'm trying to figure out why.

Change in the server the port from 443 to 58001.

If you have software Firewall on the server make sure that the port is opened there too.

Keeping in mind that my understanding of all this isn't nearly what it should be, if I changed the server port wouldn't I have to change the port forwarding on the router as well? I had this working at one point with the server port apparently 443 with the router forwarding from port 58001. But now apparently the router isn't forwarding that port anymore, and I can't figure out why it isn't.

 

[JackMDS]

I do not know why it work before, but port 443 is the https port.

"HTTPS URLs begin with "https://" and use port 443 by default, whereas HTTP URLs begin with "http://" and use port 80 by default".

See more here - http://en.wikipedia.org/wiki/HTTP_Secure

It is used by a lot of apps when they are connecting as a secure connection.

So, with your level of knowledge choose whatever port you want in the higher port count and do not mess around with 443.

I access it through https. I think I figured out the issue, I just don't know how to fix it. When it was working I had a standard cable modem connected to my ASUS router. Since then my modem was replaced with a time warner gateway, which includes a router and phone connection, neither of which I use. I believe the router portion of their gateway is blocking my port request before my ASUS can see it. But I can't figure out how to open the port on their gateway, which is an Arris TG865.

That said, you have now Double NATing from two Routers and that is a bad situation in General.

If the Aris is a Good enough Router for you, leave it as is and configure the Asus as an Access Point.

The arris is a pos as a router, that is why I run the ASUS. If I could figure out how to disable all the gateway functions from the arris I would but so far I haven't been able to. I would much rather have just a cable modem.

I have just been through the exact same situation with TWC. You won't be able to reconfigure the Arris for bridge mode yourself but tech support was able to see the problem from their end immediately and quickly solved it. Almost made up for the incompetent installer not setting it up right to begin with.
