network create non-routed without gateway no longer possible#2841
Description
Description
I try to create a L2 only network, means not routed and no gateway. However a gateway is still set. (Purpose is to create a HA network between 2 servers, where only HA heartbeat is sent between 2 nodes).
Steps to reproduce
apiclient=IaasApi(_api_configuration) ipv4withprefix=CreateNetworkIPv4WithPrefix(prefix='10.1.0.0/28', nameservers= [ '8.8.8.8' ]) print(ipv4withprefix) ###### gateway=None nameservers=['8.8.8.8'] prefix='10.1.0.0/28'###ipv4=CreateNetworkIPv4(ipv4withprefix) print(ipv4) ###### oneof_schema_1_validator=None oneof_schema_2_validator=None actual_instance=CreateNetworkIPv4WithPrefix(gateway=None, nameservers=['8.8.8.8'], prefix='10.1.0.0/28') one_of_schemas={'CreateNetworkIPv4WithPrefix', 'CreateNetworkIPv4WithPrefixLength'}###candidateitem=CreateNetworkPayload(name=name, ipv4=ipv4, routed=False, dhcp=True) print(candidateitem) ###### dhcp=True ipv4=CreateNetworkIPv4(oneof_schema_1_validator=None, oneof_schema_2_validator=None, actual_instance=CreateNetworkIPv4WithPrefix(gateway=None, nameservers=['8.8.8.8'], prefix='10.1.0.0/28'), one_of_schemas={'CreateNetworkIPv4WithPrefix', 'CreateNetworkIPv4WithPrefixLength'}) ipv6=None labels=None name='ihe01testnetwork' routed=False routing_table_id=None###result=apiclient.create_network(project_id=project_id, region=region, create_network_payload=candidateitem) print(result) ###### created_at=datetime.datetime(2026, 1, 20, 15, 37, 7, tzinfo=TzInfo(0)) dhcp=True id='c90cdb22-202a-46b2-b224-e268ec48e46c' ipv4=NetworkIPv4(gateway=None, nameservers=['8.8.8.8'], prefixes=['10.1.0.0/28'], public_ip=None) ipv6=None labels={} name='ihe01testnetwork' routed=False routing_table_id=None status='CREATING' updated_at=datetime.datetime(2026, 1, 20, 15, 37, 7, tzinfo=TzInfo(0))###### ---> while creating, gateway is still Noneresult2=apiclient.get_network(project_id=project_id, region=region, network_id='c90cdb22-202a-46b2-b224-e268ec48e46c') print(result2) ###### created_at=datetime.datetime(2026, 1, 20, 15, 37, 7, tzinfo=TzInfo(0)) dhcp=True id='c90cdb22-202a-46b2-b224-e268ec48e46c' ipv4=NetworkIPv4(gateway='10.1.0.1', nameservers=['8.8.8.8'], prefixes=['10.1.0.0/28'], public_ip=None) ipv6=NetworkIPv6(gateway=None, nameservers=[], prefixes=[]) labels={} name='ihe01testnetwork' routed=False routing_table_id=None status='CREATED' updated_at=datetime.datetime(2026, 1, 20, 15, 37, 10, tzinfo=TzInfo(0))###### ---> once created, gateway is set, although it shall be NONE.- Initialize the API
- Create a network with non_routed=True and ipv4.gateway=None
- Get details after network creation has completed
Actual behavior
Shows a gateway is assigned to subnet, and communicated i.e. to DHCP clients
Expected behavior
Network has no gateway, no gateway is communicated via DHCP.
Environment
stackit-core==0.2.0 stackit-iaas==1.1.0 Additional info
Addon: Also via stackit CLI this seems to not work.... option no-ipv4-gateway seems to be ignored? Although network-interface list shows that there is no gateway interface from the project router (only the meta interface), the network overview still shows the gateway IP.
