Multi SItes

Hi I have 4 sites details as follow

 

HQ Site 

192.168.1.0/24

Site 1 

192.168.0.0/24

Site 2 

10.0.0.0/24

Site 3

172.31.0.0/24

 

All the sites have a site to site vpn connected to HQ. How can i configured for the differenet sites to communicate among themselves? Example

 

Site 3 needs to access site 1 Data and Site 2 Needs to access Site 3 data.

 

Besides creating the sites to have site to site vpn with each other , can the different sites connect through HQ to access the required sites? 

 

Deeply Appreciate for any advice.

Hi,

if I understood your infrastructure correctly.

 

If you use vpn site at site and no advpn, you must configure the policies on the HQ site to allow flows on the VPN interfaces And then check the routing tables on each site to indicate the addresses of the remote sites.

 

Best regards,

There are two ways to do this:

 

1) Put all the sites into a zone and allow intra-zone traffic

 

2) Make policies from site 1-2, site 2-3, site 1-3, etc.

 

The method you choose depends on how granular you wish to be. If you need filtering between different devices, then the second would be your option. If you trust everything and just want then to work, then the first option.
