The Subnet should be 192.168.1.0/24, not /32.

Here it's the same, it should be 10.16.50.0/24.

Hm. When tinc is started, what happens if you run the tinc-up script by
hand like this?
INTERFACE=erix /etc/tinc/erix/tinc-up

That's tinc telling you it doesn't know about the IP address
192.168.1.150, because you added /32 instead of /24 Subnets in the host
config files.

You should not have to set a gateway. The rest of your configuration
looks fine to me, so the only problems are the Subnets and the fact that
the routes are not added by the tinc-up script.
