Problem in site to site VPN between pfSense( version 2.1) and SonicWall Pro 2040
The problem i am facing is establishment of a site to site VPN in between pfSense( version 2.1 Release ) and SonicWall Pro2040 Enhanced ( Firmware Version: SonicOS Enhanced 220.127.116.11-7e) . All of the configuration is done properly , the tunnel shows UP in SonicWall , No error in SonicWall , sonicwall can send packets but can not receive as pfsense could not send any packets or receiving any packets.
Phase 1 and 2 passes properly and established successfully.
The tunnel is not showing UP in PfSense , the error from PfSense is below -
racoon : ERROR : no configuration found for peer IP
raccon : ERROR: failed to begin ipsec sa negotiation
I am not too expert in firewall, so I will be grateful if will receive a proper guideline/solution in this regard.
