*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.

Computers on the same subnet don't route to each other.=A0 Routing is
between different networks.=A0 All of your computers will be on the same <a
href=3D"http://10.30.1.0/24">10.30.1.0/24</a> network, in
additional to their other respective networks.<br>
<br>So for example.<br><br>Computer A has the
IPs<br><a
href=3D"http://192.168.1.2/24">192.168.1.2/24</a><br><a
href=3D"http://10.30.1.2/24">10.30.1.2/24</a><br><br>Computer
B has the IPs<br><a
href=3D"http://10.0.0.2/24">10.0.0.2/24</a><br>
<a
href=3D"http://10.30.1.130/24">10.30.1.130/24</a><br><br>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.<br><br>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 <a
href=3D"http://192.168.1.0/24">192.168.1.0/24</a> or <a
href=3D"http://10.30.1.0/24">10.30.1.0/24</a> networks) so it
will send the packet to its gateway of last resort.=A0 That IP space
isn't publicly routable however so it's just going to be
dropped.<br>
<br>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 <a

it will do an ARP request (broadcast) to get the MAC address associated with the

But there is still something that I don't understand regarding the

I can put new IPs on the computers, but router will know nothing
