RE: [squid-users] IPFilter + FreeBSD + WCCP

Thanks for the clarification. OpenBSD has sysctl variables to manipulate the
gre driver:

I wish they could have done this on FreeBSD.

WCCP is not standard GRE. WCCP uses a special GRE protocol and is why
GRE implementations needs to be patched to support WCCP.

If the GRE module is not patched to support the WCCP flavor of GRE
then it will silently drop any WCCP pakets as it does not look like
valid IP traffic to the GRE module.
