** This will make the subnet a public subnet.

* You will not need a NAT gateway if this is a public subnet.

== Check the NACL ==

* Remember the NACL is stateless

* Make sure you have a rule to allow:

** All traffic outbound

** All traffic inbound

* If you want to harden the subnet after this change, then revert back to only the needed traffic.
