      I have an IPSEC VPN between pfSense and VMWare Vcloud.

      The VPN appears to be working fine, however I have a constant stream of error messages in the IPSEC logs.

      
      racoon: [IPSec]: [ <remote ip="">] ERROR: failed to pre-process ph2 packet [Check Phase 2 settings, networks] (side: 1, status: 1).
      racoon: ERROR: failed to get sainfo.</remote> 
      

      These are occurring at roughly 10 second intervals.

      I Googled and "failed to get sainfo" suggests a subnet mismatch - however I have checked and all subnets are correct.

      Settings

      Phase 1

      
      Authentication method: MutualPSK
      Negotiation mode: main
      My identifier:  <my ip="">Peer identifier: <remote ip="">Pre-Shared Key: <blah>Policy Generation: Default
      Proposal Checking: Default
      Encryption algorithm: AES 256bits
      Hash algorithm: SHA1
      DH key group: 2(1024bit)
      Lifetime: 28800
      NAT Traversal: Disable
      DPD: enabled</blah></remote></my> 
      

      This is a list of the phase 2 entries.

      
      tunnel 	192.168.0.0/24 	172.16.63.0/24 	ESP 	AES (256 bits) 	SHA1

      tunnel 	192.168.3.0/24 	172.16.64.0/24 	ESP 	AES (256 bits) 	SHA1 	
      
      

      Phase 2 settings for all entries:

      
      Mode: Tunnel IPV4
      Protocol: ESP
      Encryption algorithms: AES256
      Hash algorithms: SHA1
      PFS key group: 2(1024bit)
      Lifetime: 28800
      
      

      Any help would be appreciated.

      pfSense version:

      2.1.1-RELEASE (amd64)
      built on Tue Apr 1 15:22:21 EDT 2014
      FreeBSD 8.3-RELEASE-p14

      VMWare Vcloud Director version unknown.

        Replying to own post as this may help someone else in the future.

        I found the issue.

        On the remote side, I had defined our three (local) networks:

        192.168.0.0/24
        192.168.3.0/24
        10.1.1.0/24

        Because we had no need for the 10.x subnet to use the VPN yet, I didn't define a phase 2 entry on pfSense.

        This was causing the errors.

        Defining a phase 2 entry for the 10.x network on pfSense resolved my issue.
