# Create GW manually
All GW types can be created manually.
To create a gateway manually:
1. Click Admin – Infrastructure – Gateways.
2. A list of gateways existing in the selected system group will be displayed.
3. Click “Create Gateway”.
4. Select System Group, Division and a Root Group.
**A gateway can only belong to a root group so only root group can be selected.**
The root group is the highest level group defined directly under a division as described in [Groups](/boomerang-3-domain-administrator-manual/admin/organisation/organisation__groups.md) chapter.
5. Enter gateway Name.
6. For Transport GW a random MAC address will be entered automatically into the MAC Address field. You may change it if needed. Use hh:hh:hh:hh:hh:hh format where h are the hex digits from 0 to F. Both small and capital letters are accepted for A-F hex digits.
7. Select the gateway type.
8. For some of the gateway types, some additional parameters are needed. They are described in the following chapters describing all gateway types.
9. Click “Create” and sign.
10. A confirmation message shall be displayed.
11. Click OK.
12. The gateway shall be visible in the active gateway’s list.
