Hello,  
I'm trying to make the elastic-serverless-forwarder lambda function use AWS Private Link as output - but I'm not sure if the lambda function will use the VPC forwarder (the default one on .2) so the dns will resolve correctly ?  
I have added the correct VPC (subnet 10.36.0.0/16) to the lambda function, in this case subnet 10.36.1.0/24, and my question is if the lambda function would use the VPC dns server on 10.36.0.2 ?

Thanks  
Regards  
Kristoffer
