in short: How to setup the router to allow external host to see the outgoing source ip as the router virtual ip if the the connection is from the router it self instead of the internal servers.

my current setup, 

10.bbb.145.246 is the router ip 

10.bbb.145.217 is the virtual ip

root:~# ip route list
default via 10.bbb.145.1 dev eth0
10.bbb.145.0/24 dev eth0 scope link src 10.bbb.145.217

i need the route device itself that create the ip packet will fire using its virtual ip ,so i tried this 
10.bbb.145.246 dev eth0 scope link src 10.bbb.145.217

it failed when i checked the tcpdump
source ip showing 246 i wish to change to 217

thanks for reading
