RHEL 7.8 Servers are used in our topology.
RHEL 7.8 (SASG containing docker container having physical & virutal ip)........................RHEL 7.8(Normal Endpoint)
1)SASG has physical ip & VIP running inside the docker. Both uses 9.30.80.x subnets only.
2) Endpoint is also having a physical ip belongs to the same subnet
3) Issue: SASG is able to reach Endpoint through its physical ip. However, SASG is unable the same endpoint using itz Virtual IP (VIP).
4) Steps taken: I ran tcpdump on the all machines . I could see the packets coming in. Only communication is not happening between virtual ip and Endpoint.
5) we also have iptables running inside docker container (Virtual ip). if NAT blocks the flow, is there any debug command or any way to figure it out.
You can try adding iptables logging for NAT rules to see if any traffic is captured.
