Having problems allowing GRE outbound on production Pix

Asked by bigdog5150 in Cisco PIX Firewall, Virtual Private Networking (VPN)

Tags: , ,

Good Morning,

I have a Pix 501 in production that is working perfectly. I'm trying to allow GRE outbound  as illustrated from the doc: http://www.cisco.com/en/US/products/hw/vpndevc/ps2030/products_configuration_example09186a0080094a5a.shtml#maintask1


Adding the three lines below nullifies all rules shown in the config file below, blocking all incoming traffic. I'm not sure why this is happening and I need to get this working. Any assistance would be greatly appreciated.
