For customers already familiar with our USG, here's the good message: The interface configuration on a NSG is quite similar to setting up the USGs interfaces! DNS, DHCP ranges, Interface grouping - all of those things are very similar to our USG Series. But what if you are not familiar with the USG? Sometimes, the possibilities given might overwhelm you, and you might not know where to start. That is exactly what this article is there for then!
First of all, the NSG uses so called Port Groups. These port groups define, which of the interfaces you create on the NSG are mapped to the physical interfaces.
The screenshot shows the settings on the Nebula Cloud Center which you can do related to Port Groups. All interfaces are either mapped to Port Group 1 or 2, and the groups are linked to the physical interface.
Next is the interface itself - you can either go with the already existing interfaces LAN1 and LAN2, or create a VLAN interface. Please note that VLAN interfaces are set to tagged status on the physical interface!
Pressing the "Edit"-Button will lead to edit the interface parameters, such as DHCP Servers, Options, DNS, IP address etc. - here an example of a LAN1 configuration, using Google-Public DNS server as the DNS server for the clients connected to the USG:
For more information on the definition of the parameters, please check first the support guide for the Nebula Control Center: Nebula CC > HELP > Online Documentation > NCC User's Guide (including AP, switch and gateway monitoring & configuration) (Page 129 onwards)
An interface can also be set as a "Guest"-Interface. Guest interfaces will only be allowed by the internal firewall rules to surf the web, and will block any approach of clients communicating with each other as well as communicating across multiple interfaces:
Pressing the "Add"-Button will enable the customer to create a VLAN - the menu remains nearly the same as for LAN1 and LAN2, but gives you the possibility to set a VLAN-ID as well as a Port-Group to your preference.
This is basically all the magic there is to interfaces on the NSG - for further inquiries, feel free to contcat our support staff!
