Somebody please help me - I have no idea how to use this app.

I have a VPN account with Express VPN, and I know how to set it up on my Mac, and I've set it up on my wife's android device using L2TP. The problem is....in vpn9c - the fields have different names than what I'm used to seeing.

So, what information do I put into what fields?

I have a server address, a username, and a password, and my IPsec pre-shared key. If somebody could tell me what information to put into the following fields:

Gateway:
Group Name:
Group Pwd:
Usename:
Password:
Domain:

I would really REALLY appreciate it!!!

Thanks,
Jordan
