Windows tinc network no data despite tinc connection

[Herr Brandes]

Hi guys, thanks in advance for any answers.

Trying to get tinc up and running, I hit a roadblock though. What I’m trying to do is to connect to my roaming notebook to my company network.

All hosts on our network live in the 10.42.x.x range, netmask is 255.255.0.0.
Tinc 1.1pre14 service is running on a Windows host 10.42.2.50.
Public ports are natted through, telnetting public ip port 655 the daemon answers.
On my notebook running Windows 10 I also have tinc 1.1pre14 running.

The server is configured as follows:
--- tinc.conf ---
Name = serverwin
Interface = VPN

--- hosts\client ---
-----BEGIN RSA PUBLIC KEY-----
xxx
-----END RSA PUBLIC KEY-----
Ed25519PublicKey = yyy

--- tap/tun ---
The virtual network adapter is named VPN and configured for IP 10.42.100.3, subnet 255.255.0.0.


The client is configured as follows:
--- tinc.conf ---
Name = client
Interface = vpn
ConnectTo = serverwin

--- hosts\serverwin ---
Address = public ip
-----BEGIN RSA PUBLIC KEY-----
xxx
-----END RSA PUBLIC KEY-----
Ed25519PublicKey = yyy

--- tap/tun ---
The virtual network adapter is named vpn and configured for IP 10.42.100.2, subnet 255.255.0.0.


Pulling tinc info client on the server gives the following:
Node:         client

Pulling tinc info serverwin on the client gives the following:

Nothing answers on ping from my notebook though, pinging 10.42.100.3 times out. Pinging 10.42.2.50 times out.
Pinging the notebook from the server (10.42.100.2) also times out.

What am I doing wrong or missing here?
