**Configuring a Site to Site VPN between two SonicWalls on the same WAN subnet with same default gateway.**


DESCRIPTION:
  
When an attempt to establish a VPN tunnel between two firewalls using the same gateway IP address and subnet fails, logs in both units may show an error indicating that the remote peer does not respond to phase 1 IKE requests or no negotiation attempts at all. This happens when the upstream gateway is not configured to handle the ARP requests properly. The issue is usually observed when both firewalls are connected through the same ISP over a DSL connection when the ISP is using RFC1483 bridging mode. Static routing is used to successfully work around this problem.
