I have setup a test WAAS setup. The remote site connects to the main site through a site-to-site VPN connection. Cisco 1841 router is doing WCCP redirection at the remote end without any access lists. So all the traffic is being intercepted. I have set it up as explained in the WAAS quick config guide. File services are working fine but email, http and citrix traffic is being blocked somewhere in the network. This means WAFS is working but application acceleration is not at all working.. When I disable WCCP, everything works.
What am I doing wrong here?
Per Cisco the
Minimum Recommended Versions (IOS Routing Platforms) for WCCP w/ WAAS are
You might want to try upgrading your IOS to 12.4(10) or the T train if possible. I would start there.
Found these caveats on 12.4 code
Symptoms: WCCP service redirection may not work. In particular, packets that are rejected by a third-party vendor appliance device and are returned to the router for normal forwarding may be discarded.
Conditions: This symptom is observed on a Cisco router when NAT or Cisco IOS Firewall features are enabled on the same interfaces that have WCCP enabled.
Workaround: There is no workaround.
