            Bug ID: 112695
           Summary: impress does not listen on tcp 159 for remote
                    connection
           Product: LibreOffice
           Version: 5.4.1.2 release
          Hardware: x86-64 (AMD64)
                OS: Windows (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Impress
          Assignee: libreoffice-bugs at lists.freedesktop.org

Description:
impress not listening for bluetooth or wifi impress-remote connections on
win10/x64

Steps to Reproduce:
1. let both android and win10 be networked over openvpn
2. configure firewall to allow udp tcp, allow soffice.bin ability to open ports
3. start libreoffice, and open a ppt 
4. ensure the remote enable settings
5. connect android impress remote via IP


I was trying to get impress remote to connect to impress on win10/x64 .

Impress-remote Did not work for impress on win10/x64 neither bluetooth nor over
wifi.

Impress-Remote worked for impress on linux/x64 (fedora 26) both bluetooth and
over wifi.

open ports on win10 machine
netstat -anb

$ netstat -anp | grep -E "179[79]8"

tools/options/libreoffice/advanced/enable experimental features
> tried both enabled or disabled, what I understand is experimental is not required for libreoffice-5+

C:\Program Files\LibreOffice 5\program\soffice.bin given tcp and udp access in
firewall, all ports, all users, all interfaces, all network categories,
narrowed to 192.168.21.x


* Setup specific detail: 
tested on a openvpn TAP adapter (I don't expect it to be different )
Android runs open vpn client
Linux runs open vpn client
Windows runs openvpn client
A linux server directly reachable runs the openvpn server
tested via RDP to windows host over openvpn (I don't expect openvpn rdp to
interfere with anything)


Using netcat was able to confirm that udp/tcp ports can be opened, listened and
texted through
It is not an mtu problem or a reachability problem

temporarily allowing udp, tcp from 192.168.21.x and listening for android
connect on 1599 tcp
$ ./ncat 192.168.21.14  1599 -kl
LO_SERVER_CLIENT_PAIR
vesta
9708
nothing on 1598 tcp, 1599 udp, 1598 udp

no wifi device shows up in "Slide Show/Impress Remote", enter pin dialog
window.

It's also the the case that direct bluetooth remote also does not work. 

I feel the impress remote subsystem is not starting properly and even listening
for connections.


Actual Results:  
no impress remote connection

Expected Results:
the android-impress-remote should have connected and worked as on the linux
machine


Reproducible: Always

User Profile Reset: No, relatively clean unpolluted machine, fresh libreoffice
install
