[strongSwan] something like tinc?

Hi James,

using IPsec kernel encryption you can define a virtual IP address
to be used within the tunnel.

If you insist on a tun interface then you could use the libipsec plugin
which does all the IPsec encryption/decryption in user space if you
are willing to incur the considerable loss in performance.

Best regards
