Direct VPN tunnel over the Internet on the same subnet

I have a VPN tunnel with sonicwalls on both ends. Is there a way to have site B on the same subnet as site A?

Hi @JAlkazian ,
If both sites have the same subnet, you can set up a site to site VPN and use NAT to help the traffic traverse.
Please see the following KB article that will show you the steps how to set this up:
How can I configure NAT over VPN in a Site to Site VPN? | SonicWall
Or do you mean you are looking to extend the network from Site A to Site B? Due to routing issues, this is not possible but if they both have the same subnet, please see the kb above.
What exactly you want to accomplish with this configuration?
ideally both sites would be using the same subnet 10.3.64.0 because site B cannot reach an IP address on site A that is connected on a separate VPN on site A
Hi @JAlkazian ,
Based on your last comment, It sounds like you have 3 sites and you would like communication between all three? if that is the case, a hub and spoke VPN set up might be what you are looking for:

It's not a smart move......
You will get masses of garbage windows packets going over your network , that does not specifically need to.
also you end up with problems of broadcast packets....
and don't even get me started about multi site DNS & DHCP.....
I run something similar between multi countries.
Setup a nice subnet at each site and then NAT between locations, only for the traffic you need.
Thank you... yea, not going to go that way... much appreciated for all your guidance.
