Hello, arshadayub.

What type of encryption did you use (as well as VPN type)? For a good protection you need to use encryption at last as aes-128, turn off aggressive mode (this is why you saw a hash) for IPSec and use a tunnel mode.

Best Regards.

I'd be interested in knowing the settings used as well.

I'd recommend AES-256

Perfect Forward Secrecy

and DH group 5
