VPN address of the remote host

[Jean-Charles Andlauer]

Hello,

Please bear with my inexperience ;)

Some tinc configuration examples available on the Internet include a
statement like this:
"route add -net $subnet netmask $netmask gw $remote_ip", where
$remote_IP is the VPN address of the remote host.

Q1:
Does this statement modify the behaviour of tinc (as compared to
"ifconfig $interface $local_ip netmask $netmask")?

Q2:
If it does, is there a way to determine the VPN address of the remote
host, as this would simplify configuration of tinc a lot, i.e.
configuration could become automatic/dynamic rather than
manual/static?

Q3:
Isn't setting up a routing daemon just to get that information (i.e.
the VPN address of the remote host) a bit overkill?

Thank you for your attention, and regards,

Jean-Charles
