GRE traffic trough the pix firewall

Unanswered Question
Jul 2nd, 2007

Hi,

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.

Hi,

The link you have sended, it helped a lot, but in this case, I have to NAT i my Cisco 6006 before generate a GRE tunnel. And I also have to differentiat the traffic from same subnet to the Internet and trough the GRE tunnel. Tanks a lot again for any help.
