I'm not sure how many commits that release is behind from master but 3 years is a long time. I'm pretty sure every user of the library would appreciate an update.

Hi,
On my home network I have 4 Wireless routers. Unusual yes, but I'm sure I'm not the only person with more than 1 router.
3 routers are running in AP mode connected back to the internet router over Cat5. They don't supply IP addresses but all have the same SSID
However when I look at a UPnP scan I get 1 Netgear D6200 (not connected to the Internet) and the D6400 which is.

The D6200 is coming back first in the UPnP scan and is incorrectly being selected as the default GW.

It may not be a complete fix, but I altered GatewayFinder to exclude the D6200 which has an external IP of 0.0.0.0 and also to store the Gateways IP address using the source address of the returned Unicast UpnP packet.

This piece of code is not compatible with Android. Do I need some libraries? or is there any other solution?

import org.w3c.dom.traversal.DocumentTraversal;
import org.w3c.dom.traversal.NodeFilter;
import org.w3c.dom.traversal.NodeIterator;

        NodeIterator iter = ((DocumentTraversal) d).createNodeIterator(d.getDocumentElement(), NodeFilter.SHOW_ELEMENT, null, true);
        Node n;
        while ((n = iter.nextNode()) != null) {
            try {
                if (n.getFirstChild().getNodeType() == Node.TEXT_NODE) {
                    ret.put(n.getNodeName(), n.getTextContent());
                }
            } catch (Throwable t) {
            }
        }

Hello,

I'm assuming based on issue #8 that it won't be a problem if I publish this library on Maven. However, I'll have to publish under my domain. I will, of course, maintain your copyright info as well as your name throughout the library.

I'm also thinking about publishing a modular version for Java 9+ though it might be enough to just include an automatic module name in the manifest file... certainly would be enough for most devs anyway...

It's an awesome library that just works, and it works well.

Thanks.

Hey minecraft doesn't have your library installed. Can I distribute this jar for a networking mod? I don't see a release forums like maven and it might fail anyways.

I don't understand the license under gnu it says may convey a modified copy what the heck does that even mean can I or can I not redistribute it?

I would of course give a credits to you and a link back.

From what I can tell it's only Line 62 of Gatewayfinder that the warning is but, I would check all three classes to be sure everything is right. If this is purposeful close the issue I just don't think it would be

Currently. If a user were to look at what uPnP applications activated a port it comes up with the name of WaifUPnP, something that isn't too informative to a user

When I get some time, I'll create a pr

so I love the idea of one line but, it appears it's not working for me. I believe UPNP is enabled on my internet box and utorrent does port forward but, I am trying to make a safe program to do so.

The code prints port did open and upnp is available also says true in the loop:
Issue http://www.canyouseeme.org can't find port open for 25565. I also tried udp same result Maybe I need to config your program to port my public ip instead of my private ip????

I also read that your only looking for a default gateway my internet is xfiniti maybe you could add an option to scan for all gateways? All I need is a port to open

Code:
https://pastebin.com/0uS4guVE

Output:
port opened:true
mapping:true
true

function: UPNP.refresh()

makes your program start from scratch again and find all gateways and stuffs
This is so when people port forward and media gets disconnected client's/servers don't have to restart the game which can take as much as 30 minuets in an mc modpack.

I don't know what all to call to make a refresh method myself since you wrote It I was hoping you could write it for me.

It would be nice to have this awesome library in a popular global repository like https://mvnrepository.com/ for easier inclusion into projects.

router xfiniti:
program tested with: minecraft with lan-essentials(Not quite up to date):
https://github.com/jredfox/lanessentials

Code Ran during test run:
https://gist.github.com/jredfox/b98f0dca5da13d4d359b9fa6fcadfdb1

Test run:
while game is still running close port > doesn't always close port
while game has closed close port > doesn't always remove entry from http://10.1.10.1 internet service provider
when game is closed try and close the port.

Test run 2:
when application has been closed for several minuets close the port works

Test run 3:
when minecraft is still port forwarding close UDP port instead of TCP port and my port did get closed. Maybe your close UDP port and close TCP port are named wrong? I have an unmodified latest version of your library

Test run was tested with this code to close the port tried with both and just plain tcp which is what minecraft uses to host lan.

I hope you can make it remove the entry better since I have tried both while the program was running when it was closing and after it closed same result. Maybe it's an issue/bug with my internet service provider.

Can you eventually support this? PCP will take over UPNP very shortly and NAT-PMP routers are still used.

Some libraries like https://github.com/offbynull/portmapper have/require the port to be refreshed? What is this does your library need this or is this something that they came up with to close the port automatically if it's not opened?
