[Bug 1897580] [NEW] SG rules aren't properly applied if CIDR of the tenant network is also matches the host network CIDR

 

Public bug reported:

This error happens when using OVS hybrid firewall driver.

Steps to reproduce:

- check Compute's IPs and networks, choose the network and IP address to test this issue. For example: 172.17.3.0/24 -> 172.17.3.29
- create neutron network with appropriate subnet, set DHCP allocation pool properly, so it will include IPs for DHCP agents and the VM itself (or assign fixed IP)
- schedule VM on proper compute node
- create a rule to permit icmp traffic --> no rule is created!
