Re: [Users] ipsec stop causes total connection loss

Hi all,

A solution is to issue a "ipsec auto --delete xxx" and a "ipsec auto
--add xxxx" on both sides.
The "stop" command doesn't delete the routes.

I didn't use it up to now, but I figure that the Delete/Notify patch
makes this kind of stuff !

Ciao
