This is more of a theoritcal question then a problem. With regards to Site to Site VPN links, let's for the sake of the question say we have two Sonicwall Firewalls
.
Site A
and Site B
SonicwallA
and SonicwallB
respectively to the sites mentioned above.
1). Now if I was to create a Site to Site VPN on SonicwallA at SiteA
and set the Primary Gateway to the IP of Sonicwall B at SiteB
but didn't configure anything on SonicwallB - what connectivity would I achieve?
2). Next I would go and configure a Site-to-Site Link on SonicwallB and set Primary Gateway for the VPN to IP of SonicwallA. What connectivity would I achieve then with both active?
The reason I ask this is because a Site-to-Site VPN only establishes one tunnel, but how is that possible with two Firewalls connecting to each other via two totally seperate Site-to-Site VPN configurations?
