The ACE can do this without any problem.

Define your real server:

rserver SERVER1

ip address


Define 2 serverfarms ( one serverfarm per application, define the TCP port on your rserver)

serverfarm PORTAL

rserver SERVER1 80


serverfarm SSO

rserver SERVER1 443


Define 2 class maps:

class-map match-any PORTAL-80

match virtual-address tcp eq 80

class-map match-any SSO-443

match virtual-address tcp eq 443

Define 2 policy-maps

policy-map type loadbalance first-match PORTAL

class class-default

  serverfarm PORTAL

policy-map type loadbalance first-match SSO

class class-default

  serverfarm SSO

Define a L3 policy-map:

policy-map multi-match VIPS

class PORTAL-80

  loadbalance vip inservice

  loadbalance policy PORTAL

  loadbalance vip icmp-reply active

class SSO-443

  loadbalance vip inservice

  loadbalance policy SSO

  loadbalance vip icmp-reply active

activate this on your interface

vlan 10

service-policy input VIPS
