Running into an issue pinging from RedHat instance to a windows server instance. I have tried multiple things within the security settings with absolutely no luck. I can ping the RedHat instance from the Windows Server but I can not ping from the RedHat instance to the Windows instance.
- Updated the Security Groups for both instances to allow all ICMP traffic on Ipv4 and 6.
- Tried custom rule for ICMP to allow all traffic.
Looked at a few other questions on here also that are similar with no result. - AWS EC2 instance not responding to ping (Petr Mensik) - AWS EC2 instance cannot ping certain address (Petr Mensik)
Any ideas would be greatly appreciated.
