I've got the same problem, and nobody seems to have a solution.

Update.
It is really strange and i do not understand why it keeps choosing the same parameters even if i change the default proposal for ipsec.
I can see clearly on the log that.
I don't understand, please someone help!!

Hi, i am making progress. Due to the fact that i get the "NO-PROPOSAL CHOSEN" Error back from the server, i assume that i'm using wrong combination of Hash and encryption. The problem is that when i change the default proposal on IPSEC options it seems to me that is not changing hash and e...

Hi, i am doing my best to trying to connect my mikrotik to VPN as a client Mikrotik is connected to a modem/router on the web. All the ports are open for IPSEC to work but it can connect ONLY if IPSEC is not selected. "Use Ipsec" unchecked. There is my log output when trying to connect: 21...
