[User feedback required] Direct Connection problem - no IPv4 binding

[SpannerBracket]

Hi,

I'm struggling to get Direct Connect working. I've set these settings:

MyJDownloaderSettings: Preferred IPVersion = IPV4_ONLY
MyJDownloaderSettings: Manual Local Port = 3129
MyJDownloaderSettings: Direct Connect Mode = Allow lan/wan connections with manual port forwarding
MyJDownloaderSettings: Manual Remote Port = 3129

I've configured port forwarding on TCP 3129 to my server running JDownloader on my external router.

When I run a netstat on my server, I can only see JDownloader binding on IPv6 to port 3129. There is no IPv4 binding.

I presume the lack of IPv4 binding is why Direct Connect is not working. Any ideas how to resolve?

Jdownloader Rev: #43459
Java 9.0.4
Ubuntu 20.04

Thanks,
SpannerBracket

Preferred IPVersion only is about DNS resolution and connecting to our relay server. Has nothing to do with direct connections.
Under linux tcpv6 and tcpv4 sockets are shown as tcpv6, see
unix.stackexchange.com/questions/237731/why-are-ipv4-tcp-connections-showing-as-tcp6
you will only see two entries if you bind to ipv4 and ipv6 in seperat!

I would recommend we take a look via Teamviewer, contact me via support@jdownloader.org
Are you running FritzBox router? or any router that blocks DNS rebinding?
