I currently have a 2600 as my headend for a few GRE tunnels to 1710s. I would like to add a PIX501 to the mix. I know that you can't run GRE over the pix, but wanted to know if there are an considerations before I try to configure it. Also, are there any guides in doing so as well. I am using IOS 12.2(2)XT. I use the GRE for the routing of EIGRP. The new site for the pix will just be a lan extension, no need to route EIGPR.
