Yes :)

If the proxies are in the same IP range, you can use a persistence mask
to ensure that addresses in a given range are "glued together" for
persistence purposes.

If you're using ipvsadm:

-M, --netmask netmask
  Specify  the granularity with which clients are grouped for per-
  sistent virtual services.  The source address of the request  is
  masked with this netmask to direct all clients from a network to
  the same real server. The default is,  that  is,
  the  persistence  granularity  is per client host. Less specific
  netmasks may be used to  resolve  problems  with  non-persistent
  cache clusters on the client side.

For ldirectord and keepalived, please consult their relevant
documentation for the analogous option.
