CISCO ASA /PIX devices

This should be an easy question for firewall experts.

we have a 515e PIX that has 3 Physical interfaces (e0, e1 and e2). I assigned security levels to the interfaces. e0=0 e1=100 e2=10.

We are looking into replacing it with an ASA device.

(1) Which models would provide me with at least those 3 physical interfaces to configure those security zones?. . I get a little confused with some ASA models that come with switch ports integrated.

(2) You might also provide me with some basic "education"  about the physical and virtual interfaces on those devices.

The ASA and PIX ports configurable to subinterfaces, this means:
You able to make dot1q trunk to the switch, but is less secure than you separate it physycally

So it  looks like 5510 and 5520 would provide me at least the same physical interfaces. Right?

Would the 5505 also provide me with at least 3 physical interfaces? I do not care much about the extra security features. I just need at least to be able to configure the 3 Security Zones.

If you buy 5505, you able to configure 3 security level, becouse it has restricted licence, it means the third zone only one direction can be make traffic!!!!

If you want all zone traffic you must buy ASA5505-SEC-BUN-K9

Yes the ASA 5505 will work.  I would suggest buying the security plus add-on.

Here is some info from Cisco.

The Cisco ASA 5505 features a flexible 8-port 10/100 Fast Ethernet switch, whose ports can be dynamically grouped to create up to three separate VLANs for home, business, and Internet traffic for improved network segmentation and security.  

You could seperate the VLANs to be DMZ, LAN and Internet.

Continuing on:

As business needs grow, customers can install a Security Plus upgrade license, enabling the Cisco ASA 5505 to scale to support a higher connection capacity and up to 25 IPsec VPN users, add full DMZ support, and integrate into switched network environments through VLAN trunking support.

This just means you can actually extend the DMZ into you LAN by using Vlanning.  This will depend how your DMZ setup is at the moment and how many devices are connected?  Seperate switch, single device?

Basically with Vlanning you can have multiple virtual networks over a singal physical network.  

I hope this helps.
