С обеих сторон одновременно запустил рестарт....Правда везде в инструкции описано что ipsec в init.d находится...у меня slackware, я там не нашел такой папки при установке.
Меня еще смутило что в папке /etc/ понаделывалось куча папок с мёртвыми ссылками rc.0.......rc.6 в них ссылки K7ipsec на файл /etc/init.d/ipsec....

С этого узла все пакеты которые идут на внешку заворичивают на ipsec0

А с этого никакие не заворачивают на ipsec0, все идут в дроп..
