How to setup an VPN on a TZ170 to an NSA3500

Site A - Primary Office has an NSA 3500 SonicOS Enhanced 5.6.0.5-46o
NSA has a full DNS resolve & public IP

Site B - Remote Office has a TZ170 SonicOS Standard 3.1.5.0-2s

I want to connect workstations from Site B to Site A's netowrk & serve remote office Site A IPs via the Site A DHCP.

I can connect workstations via the SSLVPN SonicWall Netestender Client but I've never setup a VPN & I can't figure out what gateway goes where & what the networks are.

On both the TZ170 & NSA 3500 I have the IPSec Primary Gateway Name or Address: <Site A NSA IP & Site A "destination" network>

On the NSA Network Tab my LAN is "Firewalled Subnets" & the remote netowrk is the Site B's NSA Network Address Object with the Site B's IP address in that object.

On both "Advanced" Tab both have Enable Keep Alive & Enable Win Networking (NetBIOS) Broadcast.

I'm stuck - help

also, looking at the logs of the sonicwall appliances, you should get some feedback as to where it's failing in negotiating the tunnel. phase 1 or phase 2. can you post that information?

Use the wizard on the Sonicwall (upper right hand corner of pages), select other and then site to site tunnel. This will walk you through it.

Yes I checked the logs & it revealed the issue & I spoke with SonicWall & they explained the gateways have be each have the other's IP and their own local network. But I started in the logs so thanks.
