GitHub user danivogel90 closed a discussion: Define a L2 untagged guest
network, map to cloudbr1 to access company NFS services
**Problem**
I am trying to create a L2 guest network that is mapped directly to the
cloudbr1. The create network command failed with _Unable to convert network
offering with specified id to network profile_.
I can add a VLAN Range to the physical network, then I can do "create network",
but the instance will be mapped to a new bridge name/interface.
Can the configuration be created the way I imagine it?
**Versions**
- CloudStack 4.20.1.0
- Ubuntu 24.04.2
**Network**
```
bridge name bridge id STP enabled interfaces
cloud0 8000.76c30d2f0eda no vnet0
vnet1
cloudbr0 8000.aa2581097bfd no eno3
vnet2
vnet3
vnet4
vnet5
cloudbr1 8000.86803b4ff344 no eno2
cloudbr2 8000.6af97cf2fcad no eno1
```
**Configuration with CLI**
```
cmk updateZone id=$ZONE_ID allocationstate=Disabled
cmk create physicalnetwork zoneid=$ZONE_ID name="SVANet" isolationmethods=None
cmk add traffictype physicalnetworkid=$PHNET_ID traffictype=Guest
kvmnetworklabel=cloudbr1
cmk update physicalnetwork id=$PHNET_ID state=Enabled
cmk create networkoffering name="L2 No VLAN" guestiptype=L2
supportedservices="" traffictype=Guest specifyvlan=false
cmk update networkoffering id=$NETOFF_ID state=Enabled
cmk create network name="L2 Guest No VLAN" displaytext="L2 Guest SVA"
zoneid=$ZONE_ID networkofferingid=$NETOFF_ID physicalnetworkid=$PHNET_ID
```
**Error**
_Unable to convert network offering with specified id to network profile_
```
