This is the scenario:
I am running Cisco 6006 with MSFC module that is connected directly to my inside net. All the traffics are sent to inside interface Pix firewall (515E). Than firewall performs NAT/PAT to riche the outside world. I would establish GRE tunnel over IPSEC to the remote device. Is it possible to generate the GRE traffic in my Cisco 6006 than encapsulate them in IPSEC in my firewall? Tanks in advance.
