Hello,
i have a 2811 router with IOS 12.4(15)T10 where wccp enabled on the router to divert the traffic to waas appliance.
recently i add the Zone base firewall configuration, but caused some problems from communication from outside traffic.
if wccp alone is enable all communication work fine, if ZBF is enabled alone also all communication works fine.
But when both features are enabled, some traffic coming from outside stops. i had to create an access-list called waas and bind it to
wccp "ip wccp 62 redirect-list waas" and "ip wccp 61 redirect-list waas" in order to stop sending these traffic waas.
This is not the solution at all because i am exempting traffic from compression.
Please note there is no problem from inside to outside traffic
anybody has an idea on how to solve this problem, by enabling ZBF and wccp(without the exemptions) .
Please find below part of the configuration :
ip wccp 61 redirect-list waas
ip wccp 62 redirect-list waas
