[Openswan Users]

The sonic wall supports most methods of keying.
But I could only get it to inter-op with openswan with manual keying.
But that was one of the reasons to experiment with a new kernel and a
later version of openswan.

Ensure the ipsec module is loaded before starting openswan. This should
prevent netkey from getting loaded.

If a "VPN box" only supports manual keying, it should be used as a
at most. With manual keying you will never rekey your connection, so
entire duration of the VPN is using 1 key, potentially for years. The
encrypted traffic can be logged, and if a year later either openswan or
the "vpn box" is compromised and the key obtained, all communications
can be
decrypted. This is not possible when using automatic keying.
I find it hard to believe Sonic wall would sell manual keying only

A simple ADSL router these days support automatic keying and cost less
a $100. How valuable is your privacy?

Make sure to unload these with rmmod before loading the iopsec (klips)
