hi xiaolu,

we cannot change route interface ip order. not xp have primary ip address, server 2008 please apply following hotfix , leave 203.23.176.221 in ipv4 properties. after that, running below netsh command add additional ip addresses parameter:

netsh int ipv4 add address <interface name> <ip address> <subnet mask> skipassource=ture

so added addresses not used outgoing packets. more detailed information, please refer following article:

all ip addresses registered on dns servers when ip addresses assigned 1 network adapter on computer running windows server 2008 sp2 or windows vista sp2
