Forwarding through one Lan to get to another Lan.

We have Sites 1,2,3.

Site 3 is the new mothership that hosts a SharePoint server that everyone needs access to.
Site 2 is old mothership , which is now connected to site 3 via many VPNs.
Site 1 is connected to site 2 via a VPN...But needs to access the SharePoint server on Site 3.

Sites 1 and 2 are equipped with Sonicwall 2400's.

How do get Site 1 to Site 3 via site 2? I realize it would just be easier to create a VPN from Site 1 to site 3, this currently is not an option that is being entertained.

Thanks in advance.

Why is the last option not being entertained? To do it otherwise will definitely be more difficult and add unnecessary traffic to site 2.

Ultimately all sites will be going through Site 2 once dark fiber is in place...It is not being entertained because we are working on proof of concept.

On Site1 sonicwall, can you add the Site3 sharepoint server subnet to the remote subnet group in VPN policy.
On Site3 sonicwall, please add the Site1 subnet to the remote subnet group in VPN policy.

Site 1 has a duplicate subnet on Site 3, that would not work.

So the Sharepoint server on the Site3 has duplicate IP block as in Site1.

Yes, that is correct. NAT?
