The Deployment
Company A：
WAN1 IP： 61.11.11.11
WAN2 IP： 61.22.22.22
LAN IP： 192.168.10.X
Company B：
WAN1 IP： 211.22.22.22
WAN2 IP： 211.33.33.33
LAN IP ： 192.168.20.X
The A and B Company applicated two local certificates from different CA Server.
We use two SG-500 devices to be the platform. Assume that the A Company 192.168.10.100 want to build up
the VPN to B Company 192.168.20.100 , in order to download the shared documents. (Use the GRE/IPSec
packets algorithm)
