Do you have any recommendation on what I should use if WCCP is not recommended? ipfw forwarding is a very easy way to redirect traffic without changing it. PF has similar functionality. It all depends on what the appliance supports. If wccp is the only way it can eat packets, try playing with gre(4). But maybe it'll consume just plain packets with wrong IP destinations arriving on its MAC address, just the way squid on FreeBSD does. BTW, if the appliance supports ICAP, you'll be much better off running squid on a FreeBSD box and filtering content through ICAP. The filter will not be inline, and it will be an opt-in type service, so only certain traffic will need to be redirected. You'll be able to use ipfw or pf to tune the policies to a very fine degree. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

I.e. it won't need much RAM and disk space. I have yet to set up ICAP (with c-icap) in our workshop, but from discussions on squid mailing lists it seems ICAP is in a pretty usable state, both in squid 2.x and 3.x. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

Essentially, I simply need a method to redirect layer 3/4 traffic destined for anything:80 from the router to the appliance. I've got a few options now, so I'll be testing all of them in the coming days. Thanks for your suggestions.

Including this one?
rdr all port 80 to ${appliance}
Since you are leaving out the proto and tcp/udp fields this
redirection will work as expected.
