Huh? If it only works when you ACCEPT, then you seem to be using plaintext L2TP.

Did you use Marcus Müller's IPSEC.EXE tool before, or a third-party IPsec
client? Then you might need to remove the registry key
HKLM\System\CurrentControlSet\Services\Rasman\Parameters\prohibitipsec
or change the value of this key to 0. Plus a reboot.

No, this is normal because it is a point-to-point connection.
