Got a pix 501e for a small office running on 6.7. It uses DHCP to get it's outside address. I use the "static" command (and an ACL) to allow inbound traffic. However, I have only been able to identify the outside interface via it's IP address. I haven't figured a way to use "interface outside" within static or acl. So when the outside address loses it's lease and gets a new ip addr, my static command fails. Any way to do static and acls with a changing outside IP address??
