Creare connessione VPN l2tp windows7

[matteo_tgn]

Salve a tutti,
sono nuovo del forum e da qualche giorno sto cercando di configurare una VPN,
in breve:

devo connettere il mio pc da casa su rete con ip dinamico, al pc dell'ufficio che è connesso a internet tramite un box con pfSense e WAN con ip statico.

Ho seguito guide e tutorial ecc.. ma non c'è verso di farla funzionare.

ho seguito passo passo la guida

https://doc.pfsense.org/index.php/L2TP/IPsec

ma da windows creando la connessione vpn resta in " connessione in corso " per qualche minuto poi mi dà errore:

Errore 789: Tentativo di connessione L2TP non riuscito. Il livello di sicurezza ha rilevato un errore di elaborazione durante le negoziazioni iniziali con il computer remoto.

su pfsense questo è il log di IPsec
