Yes. Sorry, didn't know that windows doesn't allow this. I normally use
linux and there this is no problem. When I used windows, it was another
network, so I never had this problem.


Ok, lets try another way. Leave all as it works now.
If you use switch mode, I prefer router mode in tinc.conf
Don't know it will work in switch mode too.

Add your local subnet in your hosts files:
At tinc host 10.20.30.1
Subnet = 192.168.0.0/24
At tinc host 10.20.40.1
Subnet = 192.168.1.0/24
At tinc host 10.20.50.1
Subnet = 192.168.2.0/24

Add static route to your tinc and other computers at local network for
192.168.0.0/255.255.0.0
For lan1 this should be something like:
route ADD 192.168.0.0 MASK 255.255.0.0  192.168.0.155
Maybe you need to add 10.20.0.0/255.255.0.0 too. Add it, should be better.
route ADD 10.20.0.0 MASK 255.255.0.0  192.168.0.155
On lan2 replace 192.168.1.155 for 192.168.0.155
Check if your tinc host has routing actvated.
Try to ping 10.20.30/40/50.1 from local computer in lan1
Try to ping 192.168.1.xxx from local computer in lan1


I hope it works.
Now that I see what to do, I would not use 10.* network at all. Would be
easier to use on network for transfer (tinc hosts) maybe in
192.168.255.0/24 network and just use one ip for every tinc host. Rest via
routing like above.


ALBI...
