TCP connection requests are dropped at the load balancer or firewall when there's a quick ephemeral port reuse
Issue
- TCP connection requests are dropped at the load balancer or firewall when there's a quick ephemeral port reuse.
- TCP Connections on a RHEL8 client are stuck in CLOSING, LAST-ACK or SYN-SENT and there's a quick ephemeral port reuse
- Quick ephemeral port reuse on RHEL8, didn't happen on RHEL7.
Environment
- Red Hat Enterprise Linux
- A10 or F5 Load balancer between the client and the server
- Palo Alto, Cisco or Check Point firewall between the client and the server.
- Traffic is mostly multiple short lived tcp connections
