Computers on the same subnet don't route to each other. Routing is between different networks. All of your computers will be on the same 10.30.1.0/24network, in additional to their other respective networks.
So for example. Computer A has the IPs 192.168.1.2/24 10.30.1.2/24 Computer B has the IPs 10.0.0.2/24 10.30.1.130/24 Computer A will be able to reach computer B using it's 10.30.1.130 IP address, but not its 10.0.0.2 address. >From Computer A, when you try to ping 10.0.0.2, it will know that this IP is not on a network computer A belongs to (Not the 192.168.1.0/24 or 10.30.1.0/24 networks) so it will send the packet to its gateway of last resort. That IP space isn't publicly routable however so it's just going to be dropped. >From Computer A, when you try to ping 10.30.1.130, it will know that this IP *is* on a network computer A belongs to, the 10.30.1.0/24 network. So it will do an ARP request (broadcast) to get the MAC address associated with the 10.30.1.130 IP. The local Tinc gateway will ultimately (I believe, Guus can speak on this with more authority than I can) perform the job of proxy ARP to get the traffic to the destination on the other side of the VPN.
