When user want to establish VPN tunnel between Non-Nebula and Nebula device, they have to go to Security Gateway > Configure > Site-to-Site VPN to create Non-Nebula VPN peers on NCC.

Then you will see Availability option there, and in dropdown list, there are All sites and This site you can select.

- All sites: It means the client under VPN topology can reach others who connect with remote side. We take an example below,
If the destination is Client 01
- Traffic from Client A will be transmitted to Site 01 first through VPN tunnel between Non-Nebula and Site 01.
- Then it will be passed to Client 01 by Site 01 NSG.
- Traffic from Client A will be transmitted to Site 01 first through VPN tunnel between Non-Nebula and Site 01.
- Then it will be transferred by Site 01 NSG to Site 02 NSG to reach Client 02. (There is no direct VPN tunnel between Non-Nebula and Site 02.)
- This Site: It means the client under local site can reach clients under remote site only. We also take an example below,
If the destination is Client 01
- Traffic from Client A will be transmitted to Site 01 first through VPN tunnel between Non-Nebula and Site 01.
- Then it will be passed to Client 01 by Site 01 NSG.
- The destination is unreachable.
