hold means: any packet for the destination of the tunnel will NOT be sent in
the clear. If the tunnel is cleared, it means packets for the IP range that
used to be at the other end of the tunnel will be sent via normal routing in
the clear.

You need to enable nat_traversal, set virtual_private accordingly, and add
rightsubnet=vhost:%no,%priv to the 'server' side. Having both behind nat
complicates things further by needing port forwards, and is really a poor
way of setting up a vpn. Try to avoid it if possible.
