NACL rule allowing 0.0.0.0/0 to access "Subnet 1"
Security Group rule in "Security Group 1" that allows 0.0.0.0/0 inbound
Security Group rule in "Security Group 1" that allows outbound traffic to 0.0.0.0/0
NACL rule allowing 0.0.0.0/0 to access "Security Group 1"

You must allow traffic through the NACL and through the Security Group to access the instance. If there is not an Outbound allow setup in the NACL, you may need to set that, but an outbound rule for Security Group 1 is not necessary as security groups are stateful.
