I am extremely new to Cisco Pix and I've been asked to look into purchasing a possible upgrade to ours. I currently have a 515E which I am going to send to another site once I get the new one. My Pix is primarily used for VPN access to my network. Once I get the new one I'd like to set up a site-to-site VPN for failover. I need assistance on which device to choose. Should I go with another 515E, the 525, or look into the ASA firewalls?
I would definitly go for the new ASA firewalls, they are more powerfull and have more expansion options than the Pix series. It wouldn't go for the 525 because just doesn't match the ASA, and the DC power supply is EoL and EoS.
Thank you for your response. And it does help! Although, here's a question. I am going to send my 515E to another site. If I go with the ASA5510 will I be able to set up a site-to-site VPN for failover?
A site-to-site VPN would make an excellent failover for a Leased Line. Just keep in mind that you'll need a device, like a router, that keeps track of availability of the main route (Leased Line) to the other office.
