The remote's router (232.133) is kvetching; it doesn't know how to reach
Typically, you must be able to reach the host normally for IPSEC to work.
If you can't ping or traceroute .232.52, it's either down or its address
changed, or the routing tables in .232.133 changed.
Another possibility is that the remote is not set to 'auto'; that is, the VPN
must be started manually from the remote end.
