Racoon: [Unknown Gateway/Dynamic]: DEBUG: 92 bytes from

[rsumook]

My Pfsense version: 2.0.1-RELEASE (i386) both SITE A and SITE B
SITE A:
bandwidth
Downstream Up to 11Mbps
UpStream: 1Mbps

Site B:
Bandwidth
Downstream: Up to 3Mbps
Upstream: 512 Kbps

Status: Connected Succesfully

On SITE B:
We deployed two IP Phone Connected to SITE A.
We deployed One Computer desktop so that user can able to access our Web based program and other program thru IPSec
and also there is a CCTV running in the SITE B, and we can able to browse it to SITE A using local IP Address.

My problem is about sometimes slow connection and lost connection
when PC tried to browse our webbased program it takes long to access it
and our IP Phone sometimes and suddenly disconnected

my main concern here is about IP Phone I've checked the logfile and i found this:

May 16 01:46:25 racoon: [Unknown Gateway/Dynamic]: DEBUG: 92 bytes from 119.92.xxx.xxx[500] to 119.92.xxx.xxx[500]

May 16 01:46:25 racoon: [Unknown Gateway/Dynamic]: DEBUG: 1 times of 92 bytes message will be sent to 119.92.xxx.xxx[500]

By the way my SITE A config as STATIC IP in WAN
SITE B config as PPPoE Configuration

Im not sure if the problem is PPPoE because its dynamic

Thanks
