The problem i am facing is establishment of a site to site VPN in between pfSense( version 2.0.1) and SonicWall Pro2040 Enhanced ( Firmware Version: SonicOS Enhanced 126.96.36.199-7e) . All of the configuration is done properly , still i got the following error in sonicwall -
Phase 1 and 2 passes properly but problem with "Payload processing" i found that it could be for shared key mismatch but I double check , no mismatch with shared key in both firewall . It also shows in sonicwall that tunnel is active-
The log from pfSense is below -
In pfSense the tunnel shows inactive .
I am not too expert in firewall, so I will be grateful if will receive a proper guideline in this regard,
