We have a number of AWS EC2 instances within the same AZ that transmit large amounts of network traffic to each other What changes do I have to do? Any suggestions? Thank you in advance! @PhilipTreacy @Greg_Deckler The AWS services like ELBs and Route53 understand TCP connections, and the HTTP protocol, but they do not understand FTP Let’s try to understand the need for a connection termination procedure in layman’s terms In addition to ICMP echo requests, hping3 supports TCP, UDP, and RAW-IP protocols 2 Answers Sorted by: 3 Using Lambda as a client to access a server is trivial, you can easily create most types of TCP connections from a Lambda outwards Deep Security is configured to allow a maximum number of TCP connections to protected computers In NGINX Plus Release 9 and later, NGINX Plus can proxy and load balance UDP traffic Source: Custom; in the blank box to the right enter the Private IP address with /32 added to the end mshetty@mshetty-mac ROSA % aws ec2 authorize-security-group-ingress --group-id ${RDS_VPC_SECURITY_GROUP_ID} --protocol tcp --port 3306 --cidr 10
