You have not stated anything about a problem. We cannot help unless we
now what is going wrong.

Finding the problem can be time consuming or tricky unless you are
fairly familiar with TCP. The "Troubleshooting" section on the tproxy4
page has many hints about what can go wrong and how to find/resolve them.

  "ip link show"

... lists the active interfaces. GRE should be one of them when open.

TPROXY and WCCP are relatively independent operations. Both equally
troublesome and complex.

It is worth checking that TPROXY is fully operational and working before
adding WCCP tunneling on top to complicate things further.
  You can test that by having the squid box as router for your
workstation instead of the Cisco.
