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.
