I am trying to use bluecoat proxy for web filtering. I have configured ASA with WCCP and wccp status is usable on both sides. ASA is redirecting the traffic to proxy. proxy client and bluecoat proxy are both in different DMZ zones but same physical interface.
gig0/1.100 192.168.100.100 Client IP
gig0/1.200 192.168.200.100 Proxy IP
appropriate access lists for client and proxy are configured.
proxy to client full ip access is open. I can see traffic reaching to bluecoat and bluecoat also sending returning traffic through GRE tunnel but somehow returning traffic is not reaching to client.
I captured traffic on ASA and i can see that ASA recieved GRE encapsulated returning traffic on gig0/1.200 but it is not passing to client on gig0/1.100.
Could you please help me to troubleshoot the problem.
