Amos,
I just did a TCP dump and I think my problem is the GRE packet. It is being
listed I think as unknown. Shouldn't squid be able to pick the packet up
and open it? The Cisco sees squid and relays the information good but it is
stopping at the squid box. Any ideas? I am just google'ing around no set
how to.

Thanks
