Can Private NAT Gateway be configured as a target for the Network Load Balancer?

Question

I need to forward traffic received from Site to Site VPN to another VPN, but SNATing is required before packets can be sent through ipsec tunnel.
I am thinking of using PrivateLink with Private NAT Gateway as a target for the Network Load Balancer.
Is Private NAT Gateway as NLB target a supported configuration?
If yes, then how to set up health checks for target group?

Answer

The following are the possible target types for a Network Load Balancer:

`instance`

The targets are specified by instance ID.

`ip`

The targets are specified by IP address.

`alb`

The target is an Application Load Balancer.

So you wont be able to configure a Private NAT gateway as a target for an NLB

If you are looking to establish connectivity between VPNs have you looked at VPN CloudHub functionality?
