Exchange 2003 -virtual ip get confused

[zillah]

I am pretty sure that we are using 192.168.2.23 as virtual ip address for our two cluster exchange win2003 servers (EX1, EX2). We have used 192.168.2.23 within PIX, and mail firewall,,,etc

ip address for EX1 192.168.2.13, ip address for EX2 192.168.2.14

But when I checked these two snapshot , I got confused, because I have seen two ip addresses:

192.168.2.22 and 192.168.2.23 ?
