Public bug reported:
Description of problem:
Later updated subnet gateway leads to IP address conflict with DHCP pool range.
How reproducible:
100%
Steps to Reproduce:
Log in as demo user.
1. Project - Network - Networks - Create Network
2. network "test_net", subnet "test_subnet", network address 10.0.0.0/24, IPv4,
tick Disable Gateway, Create
3. click to test_net row, click to Edit Subnet for test_subnet row
4. untick Disable Gateway, gateway IP 10.0.0.1, Next, leave Allocation Pools
unchanged, Save
Actual results:
Computed Allocation pools is "10.0.0.1,10.0.0.254", click to Save cause red
alert:
Error: Failed to update subnet "10.0.0.0/24": Gateway ip 10.0.0.1 conflicts
with allocation pool 10.0.0.1-10.0.0.254
Expected results:
it should exclude the IP of gateway from the DHCP pool, so:
10.0.0.2,10.0.0.254
