tinc - Dec 2017 - Having problems connecting

Parke,

Thank you for your suggestion, but I am already using those subnet settings.
And how could they be wrong if the two peers start communicating at some point
without changing the settings?

Henk

What Subnet= settings have you used in each hosts file on each host?

In the hosts files, you might want to try setting each host's Subet= to its
own <VPN ip address>/32.  For example:

On the first:
Subnet=10.23.23.1/32

On the second:
Subnet=10.23.23.2/32

The subnet of a host (in the host's hosts file) is different from the subnet
of the VPN interface on the host.

I believe there is a difference, with Tinc, between nodes connecting
to each other, and nodes deciding to route VPN traffic to each other.

Have you tried turning off the Windows firewall at both nodes?

-Parke

One of the nodes is running without a firewall. The other is on a public Azure
server and can't run without firewall. It is running without firewall on its
own (10.23.23.1) network card.

How could the firewall do this when it starts running after some time without
changing anything to the firewall?
