EC2 Instance Will not connect to internet

Check the Following

Internet Gateway

• Check the subnet has an Internet gateway

• Check the internet gateway is associated with the subnet

• • 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

• • It must have matching sets of rules

• Make sure you have a rule to allow:

• • All traffic outbound

• • All traffic inbound

After this change is made, change it back after the internet download.

The NACL will provide an additional layer of security.
