Hi Henrik, thanks for your continued help. I changed the GRE tunnel end point and the wccp2_router statement to match the router id of 150.125.127.142 but now squid and the router don't negotiate. As you can see here below, there is a mismatch in the I_See_You packet IDs. May 10 13:12:39.011 GMT: WCCP-EVNT:S00: Here_I_Am packet from 150.125.125.185 w/bad rcv_id 00000000 May 10 13:12:39.011 GMT: WCCP-PKT:S00: Sending I_See_You packet to 150.125.125.185 w/ rcv_id 00000002 ULAN-ISSR#sh ip wccp web ULAN-ISSR#sh ip wccp web-cache d WCCP Cache-Engine information: Web Cache ID: 150.125.125.185 Protocol Version: 2.0 State: NOT Usable Redirection: L2 Packet Return: L2 Packets Redirected: 0 Connect Time: 00:00:16 Assignment: MASK ULAN-ISSR# Here's my squid.conf: wccp2_router 150.125.127.142 wccp2_version 4 wccp2_rebuild_wait on wccp2_forwarding_method 2 wccp2_return_method 2 wccp2_service standard 0 I have also tried forwarding/return_method of 1 with the same results. Any thoughts? Thanks again, -- Chad On 5/10/07, Henrik Nordstrom <henrik@xxxxxxxxxxxxxxxxxxx> wrote:
