IPSec from EC2 with NAT 1-1

Thu May 09, 2019 11:41 pm

I have been trying to connect to a site to site Cisco VPN server with no success. I get:

phase1 negotiation failed due to send error.

I know that the fact that my VM with Mikrotik has a private IP that is a Static NAT with a public IP can add some complications.
Can anyone guide me please on how to proceed?
I can post any export that will help.

You didn't use this public IP address that you don't really have in router's IPSec config, or did you? Because that could cause send error.
People who quote full posts should be spanked with ethernet cable. Some exceptions for multi-topic threads may apply.
