How to reach new VMs in a VPC/AWS environment
I'm very new to the network/pfsense world. so probably my question will not be very clever.
However, I created a VPC in AWS and I have put pfsense as mainrouter/firewall, therefore if all the the VMs inside the VPC want to go out from the VPC they should pass through pfsense.
My question is: since I can create/shut down as much as VMs I want, How can pfsense knows that there are new VMs and hence new IP addresses? there is a protocol that allows me automatically to know if there are any changes in my VPC?
Thanks for your help!
