Routing to a VPN from Sonicwall

We have a Meraki router that connect's us to our cloud software provider.  I added the route to our switch (that does all our routing) and everything works perfect when locally connected.

When I get home and try to connect from a VPN to our Sonicwall, I can no longer access that site.  I have the Sonicwall set to pass all traffic from me to the sonicwall.  My IP address is the exact same subnet that I would get if I plugged in locally.

Do I need to add a route in my Sonicwall for this?  My brain is not functioning right now.

Usually VPN subnets will be different than LAN subnets.

Since you are connected to sonicwall VPN and assigned your LAN ip address, the forward traffic from your vpn connected to machine to office site will work, but the return traffic is an issue.

since you are ip as same as LAN, switch will not route the return packet to sonicwall, in which you are logically connected.

forward traffic  your home machine -- sonicwall -- switch -- lan
return traffic  lan -- switch -- sonicwall -- your home machine

You might be need to have a separate subnet for the VPN and add route on the switch for the new vpn subnets towards sonicwall lan interface.This will resolve your problem

did you add a route to the cloud network in the vpn configuration. check with a route print on youre client. i think youre remote client does not have the network present.

you also need to add the network behind the vpn to youre site 2 site connection to the cloud. or nat all the traffice from the vpn with destination the cloud with the external ip of the firewall. also something we did in the past.
