WCCP ACL not redirecting traffic to McAfee Web Gateway

klopez138
Level 1
Level 1

We currently have WCCP configured on a Cisco 4500X switch. We have an ACL (REDIRECT_CLIENTS) where hosts and ranges are configured to filter which hosts get proxied to the McAfee Web Gateway (MWG). We have not seen any hits on the ACL for traffic being redirected to the MWG nor do we see traffic when doing a live trace from the MWG console. I've posted sample configs and several outputs from wccp show commands below (Addresses have been scrubbed for security). Any help with this issue is greatly appreciated. Thanks.

 

 

ip wccp source-interface Vlan777
ip wccp 51 redirect-list REDIRECT_CLIENTS

 

interface Vlan136
 ip address XXX.XXX.36.1 XXX.XXX.XXX.XXX
 ip helper-address XXX.XXX.0.80 (for DHCP)
 ip helper-address XXX.XXX.0.81 (for DHCP)
 ip wccp 51 redirect in

 

interface Vlan151
 ip address XXX.XXX.32.1 XXX.XXX.XXX.XXX
 ip helper-address XXX.XXX.0.80 (for DHCP)
 ip helper-address XXX.XXX.0.81 (for DHCP)
 ip wccp 51 redirect in

 

ip access-list extended REDIRECT_CLIENTS
 permit tcp host XXX.XXX.36.147 any eq www
 permit tcp host XXX.XXX.36.147 any eq 443
 permit tcp host XXX.XXX.32.69 any
 permit tcp host XXX.XXX.32.70 any eq www
 permit tcp host XXX.XXX.32.70 any eq 443

 

sh ip wccp

Thanks for the reply but it appears that our issue was due to cables being moved on the ESXi host where the MWG virtual appliance was hosted. Cables were moved, port channels were reconfigured, and arp tables were not cleared. Our WCCP access list is now seeing hits and sending traffic to the MWG.

You are using GRE redirection. Change it to L2 redirection and let me know
if it fixes. it. You can change it from MGW
