[Openswan Users] Proxy arp for virtual IP address

I have
  left=%defaultroute
in the conn %default section, that should work, right?

And the tunnel is established and working. The address 192.168.1.241 is
automatically added to the eth0 interface, which is very nice.

Ok. I could do that.

But what if, in a different situation, I have a block of public IP
addresses instead of 192.168.1.0/24, and I want to "extrude" part of
that block to a road-warrior? Then I cannot choose the virtual IP
address at will, it must be from the same subnet.

There are instructions for this in the Openswan documentation,
  http://wiki.openswan.org/index.php/AdvancedConfiguration
under "Road Warrior with virtual IP address". It says I should set up a
proxy ARP entry, as I described, but that doesn't seem to work for me.
