 FIREWALL Cisco PIX525
I'm thinking about using a CISCO PIX525(replacing the present PIX515) as a device for my firewall protection. What is the best common practice in the industry for setting up this device and publishing my VPN IP range?

Answer Wiki:
I don't know that there's best common practice for this device...It really just depends on your business needs. I wrote some <a href="www.principlelogic.com/docs/Firewall_Best_Practices.pdf">general firewall best practices</a> that may help. Let us know if you have any specific questions. ==================== For some general best practice documents always consider <a href="http://csrc.nist.gov/publications/PubsSPs.html">NIST publications</a>. Check out the Special Publication 800-41 Guidelines on Firewalls and Firewall Policy and it's proposed revision. In the IT trenches?

First I would ask why are you wanting to do this. The PIX515 you have is a good device for almost all sites up to a big medium sized business. The 525 is really for large corporate business. It is considerably noisier as well. The only advantage is that it is faster and allows Gigabit Ethernet interfaces (although they can not pass traffic at this rate due to hardware limitations in the PIX itself).

Both run exactly the same operating system, so anything you can do on the 525 you can already do on the 515.

If you want to change the config, to make it more robust, or to add new features, you can already do this with the PIX515, no need to change.

If you are looking to replace it anyway, then you should really look at the Cisco ASA5500 series, as these do everything that the PIX will do, but are MUCH faster, and have more interfaces and features as standard. Plus thay have additional modules available for virus filtering, IPS function etc.
