I have a PIX 515E that I am currently using as our main firewall, attached to a T1. I am getting a 4mb connection (over 10mb ethernet) at a colo facility, and I would like to move this PIX 515E over there. In order to do this, I need to take a PIX 515 that I have and get it to work identically. I have copy/pasted the config from the 515E to the515, I have copy the 515E's config to a tftp server, and then download it to the 515 by tftp. The PIX 515 is somewhat functional.
Each unit has 64MB RAM, 16MB Flash, UR License, VAC card, and 4 FE card. The 515E has PIX OS 6.3(4), and the 515 has PIX OS 6.3(5). I have used a diff to see if there are any major changes after loading, and I see none. The PIX 515 works for access from Inside to DMZ and Outside, and from the DMZ to Outside... but none of the ACLs work for traffic from Outside to DMZ or Inside, or DMZ to Inside.
