Site to Site VPN

[emmalj]

Good Morning All

I'm hoping someone can help or point me in the right direction. I have never setup a site to site VPN before and seem to be struggling with possibly the easiest settings. If I give you an insight maybe that will help, heres goes...

I have a Sonicwall Pro 2040 and the customer I'm trying to connect to has a Juniper SSG550

The sheet I have been given for parameters are

Site B = Customer
VPN Box Model: Juniper SSG550
VPN Public IP: 194.XX.XXX.6
Encryption Domain: 195.XX.XXX.1

Site A = Me
VPN Box Model: Sonicwall Pro 2040
VPN Public IP: 194.XX.XXX.227
Encryption Domain: 172.XX.XX.XX (this is what they have given us)

With regards to the general option of adding in a VPN, where do these settings go?

Any help would be great

Thanks in advance
Emma
