I have similar problem.
i am trying to connect to zeroshell l2tp VPN from a client behinde a NAT.
When i enable NAT-T option in zeroshell, i’m reciving:
ERROR: such policy does not already exist: “93.175.xxx.xxx/32 91.205.xxx.xxx/32 proto=udp dir=in”
ERROR: such policy does not already exist: “91.205.xxx.xxx/32 93.175.xxx.xxx/32 proto=udp dir=out”
but when im first connect from NAT machine, then from machine behinde NAT all working till i reboot server or restart l2tp daemon
I’m using Release 1.0.beta12, client – WinXP SP3 full updated
same error i am reciving even when connection OK. But if im not connecting from NAT macine beforehand connection from machine behinde NAT stop at this lines.
