if you want to forward the traffic to another ip for a specific port, why don't you create a new serverfarm with the new real server ip address and then create a new vserver to handle this particular traffic
ie:
serverfarm regular
real x.x.x.x
ins
!
vserver regular
vip x.x.x.x /0 any
serverfarm regular
inservice
!
Then ADD
serverfarm special
real x.x.x.x <=== new real ip
inservice
!
vserver special
vip x.x.x.x /0 tcp 23
serverfarm special
inservice
!
This is the way to do it.
