Ipsec reroute real IP subnet problem

[machiasiaweb]

Hello,

I have created a ipsec tunnel to reroute whole real IP subnet to another site

Following is my setup

–--
Site A

WAN IP: 209.111.100.1
LAN IP: 111.222.333.1

IPsec route rule
Local Net: 0.0.0.0/0
Remote Net: 111.222.333.0/28

Site B
WAN IP: 234.241.51.1
LAN IP: 111.222.333.2

IPSec route rule
Local Net: 111.222.333.0/28
Remote Net: 0.0.0.0/0

Every thing is work fine.  My PC behind to Site B with IP 111.222.333.x/28 can be access in/out between Internet.

Q. Now the question is When I checking the WAN IP of PC at Site B will be use.  The IP shown is 209.111.100.1 which is Site A WAN IP.  How can I using 111.222.333.x/28 IP?

Thanks!
