Hm, I've heard rumours that there's been some WCCPv2 bugs in the SXF code. Yah, there's an unrelated bug resolved in 12.2(18)SXF7 and a couple more in previous releases but nothing related to GRE.

Just set wccp2_forwarding_method 2 in squid.conf. See if L2 redirection does the right thing. Keep the iptables rule but toss the GRE tunnel. (I'd also suggest trying mask assignment over hash assignment with Squid-2.6 but apparently mask assignment is causing Squid to crash. I'm testing a workaround atm. It won't matter unless you're doing quite a lot of traffic and you notice the MSFC CPU usage go way up.) Adrian -- - Xenion - http://www.xenion.com.au/ - Hosting and Commercial Squid Support -
