Hi Stephen,

Don't bother with `push`, it's definitely not the way to go.

The problem now are your either the ESP algorithm proposals and/or the
traffic selectors (`left|rightsubnet`).  Start with
`rightsubnet=0.0.0.0/0` as that's what's usually used for roadwarriors
(if L2TP should be used you can experiment with restricting the
ports/protocols too).  If you still get a NO_PROPOSAL_CHOSEN notify try
adding `esp=aes128-sha1-modp2048` (that matches the IKE proposal,
however, if you actually have more specific information regarding the
ESP/IPsec proposal from your admin, use that).

Regards,
Tobias
