Hello Cezar,

I've not really got a tunnel. It's just setup as per the Squid docs to
have FreeBSD think it is. The Cisco just sends the packets encapsulated
in gre to the FreeBSD squid box. The tunnel is setup so FreeBSD will
strip the gre headers and present the system with the original
encapsulated packet on the gre0 interface.

I can see the encapsulated packets via tcpdump on gre0, and I can also
see the packets hitting my ipfw fwd rule when I turn logging on for that
rule. But I never see the forwarded packets, they just disappear!

Yes, the Cisco happily sends the packets and sees the cache.

Yes, the cache works perfectly without issue.

I've not tried version 2, but I will try it now.
