Hmm... should have been some info from the WCCP_I_SEE_YOU here... would
have expected Change Number and Receive ID to be updated.

This indicates your Squid is not accepting the WCCP_I_SEE_YOU messages
from the router for some reason. Investigating.. Ah. Please file a bug
report with this information and I think I may have a patch for you.
