Need to connect bidirectionally ( connection can start in each direction ) from EC2s on VPC to on prem servers, with certain restrictions.

Question

We need to connect bidirectionally ( connection can start in each direction ) from EC2s on VPC to on prem servers, with below restrictions:
* NAT cannot be used ( protocol doesn't allow it )
* Public address space need to be used on all flows
* Connection need to be done using Direct Connect using Private VIFs

Can anyone suggest here, best solution approach for such implementation.

Answer

Hello.

I think the following two statements are contradictory.  
Why go to the trouble of connecting your VPC and on-premises with DirectConnect's private VIF, but do you need to use public IP space?  
If you connect with DirectConnect, on-premises and VPC can communicate.  
I don't think there is a need for a public IP address.
