Need your suggestion with cisco PIX-515e

[cisco99999]

Hello,

For my network, i need something to secure my client computers, so i was looking for Cisco PIX-515E for my current network. Currently i have cisco 2621xm on my network now but i don't have firewall on it.

Here is my current network:

T1 -->Netopia-->cisco 2621xm ---> switch 24 ports--> local computers.
i set dns server 10.10.0.1, dhcp server and default gateway 10.10.0.1 on cisco 2621xm, so all local computers are grabbing the same infos from cisco 2621xm. So far this method is working fine for my network.

My questions for cisco PIX-515e are:

+ Can I use Cisco 2621xm with cisco PIX-515e on same network?
It's gonna be something like this:
T1 -->netopia router--> cisco PIX-515e-->cisco 2621xm--> switch 24 ports--> local computers.
Is this possible ?

+ IF i like to use cisco PIX-515e only on my network, does cisco PIX-515e will do the same jobs (dhcp,dns,vpn..) like cisco 2621xm ?
Here is what i was thinking to do later if possible:
T1-->netopia -->cisco PIX 515e-->switch 24 ports -->local computers.


+ Be honestly, this is the first time of using PIX so i'm very confuse, Please tell me what would your suggestions in this case !

Thanks alot.

By the way, what is difference between Cisco PIX 515E Restricted Bundle and Cisco PIX 515E Unrestricted Bundle ? Which one is better to get ?
Thanks

The main difference between the restricted bundle vs the unlimited is the failover features. The PIX515E will do all that except dns. You will need an internal server or external server for that function.
If you are getting a new device, then I would recommend the ASA5505 or the ASA5510. They have beefier hardware and the latest software. If you aren't doing complicated routing or integrated services then these will serve you well enough in place of the router.

How about this case below ?

T1 -->Netopia--> cisco PIX515E-->cisco 2621xm-->switch--> computers.
This case, Cisco PIX515E will be firewall only, and cisco 2621xm will doing local dhcp,vpn, dns server.


And another case:
T1 --> Netopia --> cisco PIX515E ---> switch --> computers.
In this case, cisco PIX515E will doing dhcp, vpn but not dns. I am going to use ISP dns in this case, is this possible ?

Please tell me what case possible and what would you refer ? Note: i already have cisco 2621xm. Thanks
Thanks

I would leave the 2621 out of the loop and just use a Cisco ASA 5505. I am sure all your router merely does had out public DNS servers via DHCP and the ASA can do that.
