, when the destination IP used in the PBHK ACL (162) matches the redirected server IP

class-map type traffic match-any class-l4r
match access-group input 152
policy-map type service ser-l4r
class type traffic class-l4r
redirect to ip 200.0.0.2
ip portbundle
match access-list 162
source loopback 1
access-list 152 deny tcp any host 200.0.0.2
access-list 152 permit tcp any any
access-list 162 permit tcp any host 200.0.0.2
In
, when the destination IP used in the PBHK ACL (162) is not the same as the redirected

class-map type traffic match-any class-l4r
match access-group input 152
policy-map type service ser-l4r
class type traffic class-l4r
redirect to ip 210.0.0.2
ip portbundle
match access-list 162
source loopback 1
