Greetings,
I have a Sonicwall NSA 3500 firewall and I just cannot get it to connect to the Azure VPN, here are the current settings at both ends:
Azure

Address 10.4.0.0/16
FrontEnd 10.4.2.0/24
Backend 10.4.3.0/24
AD 10.4.4.0/24
DNS Servers 10.0.X.X
Connectivity connect to local network is ticket, gateway subnet is 10.4.1.0/24
Sonicwall
Policy type is site to site
Auth Mode IKE using preshared key
IPSEC Primary Gateway 168.63.X.X
Preshared key is copied from Azure
Local IKE ID IP Addy 194.217.X.X - my external IP
Peer IKE ID IP Addy 168.63.X.X - Azure gateway IP
Network
Local Network is firewalled subnets
Remote network is the address object I set up for the Azure ip range

LifeTime (seconds) 28800
IPsec (Phase 2)

Can anyone spot my error, the VPN just will not connect. I get occasional phase 1 connections then they fail and never get a phase 2 connection at all.
Any help you can give is greatly appreciated!!
