Great video! I would have been nice if you would have discussed the s3 endpoint connection and the lambda eni connection. Otherwise, it is not clear why they were included in the diagram.

[@gouravchoubey860]

As mentiond ,,by default NACL allows everything so even if outboud rule is not defined for stateles outbound transmission through NACL it will allow? Until is is blocked by specific NACL rules?

Very good revision session for me.

[@knowledgeindia]

please share with your friends as well.. Look at our VPC playlist completely..

[@venkatasheshagirid1296]

Hi - When the security group are stateful , wherein outbound rules need not specify . In the AWS console for the security group there is provision to add outbound rules . On what scenarios can we specify the out bound rules. Can you please explain

[@gratecircle]

Please make more of practical QA videos. Very helpful :)

[@iambmk]

if we block port 22 at subnet level ie at NACL can we SSH any instance from the same subnet?

[@knowledgeindia]

very good question Mohan. traffic flowing between 2 instances in same subnet would not be restricted by NACL rules. NACL rules are applied at Subnet boundary. .. If you find KnowledgeIndia helpful, please share with your friends good videos of our channel..

[@theamitdost]

KnowledgeIndia - AWS Tutorials but how will we ssh to any machine of same subnet in first place ...¿

[@gouravchoubey860]

what excatly is the role of NAT gateway apart from forwarding the traffic to internet gateway? how it adds to security

[@livelifenjoy]

Hello Knowledge India, I have a quick question ,with regards to statefulness of Custom Security group of Custom VPC, when we create a new Custom VPC and Custom Security Group for that VPC , that Security has Implicit Deny for all Incoming Traffic as there is Explicit Allow mentioned , however it has Allow all for Outbound Rules , hence now the question is : If i allow port 22 as inbound rule and then logonto one of the instance to issue a curl command , as command is initiaited from within the instance which has a security group applied with only incoming as port 22 , but allow all for outbound , so will the HTTP response be handled gracely by the instance as it has been initiaited from itself and keeping the property of statefulness ?? Regards Rahul

[@knowledgeindia]

Yes. because CURL from EC2 instance would be an Outbound and you have Outbound allowed ALL. so traffic goes out and because it is stateful, it also allows response of CURL to come back. You can help us by sharing the videos with your friends on LinkedIn/Facebook.

[@rajeswarirajeswari5019]

why do we have Nacl as stateless as it invalidates having sgs as stateful right. as if sgs are stateful then it’s extra overhead in nacl to specify an outbound so as to allow the out traffic otherwise there is no use of sgs configurations

[@knowledgeindia]

It would look that way in the start. Though, in practical scenarios, we have everything allowed in NACLs (both inbound & outbound) by default. so, you typically only get into adding DENY rules in NACL as per your requirement.

[@nalamsaivishnukanth6789]

Hi Sir, I have 2 doubts, 1. if the ACL is Subnet level security then why the default ACL is related to VPC? why there is no option create different types of ACL's for different subnets? 2. if we enable auto assign Pubilc IP Address option as mentioned in the first video at subnet level, will EC2 instances launched at private subnet will get public ip address? and is it useful to access? I am seeing your videos from starting from this playlist and got these doubts. and the explanation is very clear and useful sir. thanks a lot for providing these videos which will be very useful.

[@sundar7368]
