Pfsense 2.02 Ipsec VPN goes down randomly
-
I have tried enabling and disabling "Prefer older IPsec SAs ", tried disabling NAT-T but still no luck.
This my ipsec vpn configuration.

Life time : 1800racoon: [–-------]: INFO: initiate new phase 1 negotiation: x.x.x.x[500]<=>x.x.x.x1500]
racoon: [–-------]: INFO: IPsec-SA request for x.x.x.x1 queued due to no phase1 found.
racoon: ERROR: failed to begin ipsec sa negotication.
racoon: ERROR: phase1 negotiation failed due to send error. b52634c42b55942e:0000000000000000
racoon: INFO: begin Aggressive mode. -
Normally 'queued due to no phase1 found' and 'phase1 negotiation failed' means that Phase1 settings aren't matching between the two endpoints. What device is the remote endpoint?

"racoon: ERROR: phase1 negotiation failed due to send error" is what happens when you have a misconfigured PPTP server and a client disconnects. PPTP server should never use an assigned IP of any sort, especially WAN, as its server IP.
