I work with a software company. We currently have 160 user's. We have >

Cisco 515e Firewall ( We dont have failover firewall )

Cisco 1841 Router

3 COM layer II switches

1 quantity of Cisco catalyst 3560 layer III switch

1 linux running proxy server.

Requirement >

I am looking for a all in 1 solution.

I know Cisco's ASA. But I haven't worked on it at all. I just went through Cisco's

documentation. I want a single box which can be a DHCP server, A Firewall, a router & AAA server.

Anybody can suggest flexible appliance from Cisco Systems which can mainly handle following tasks >

Firewall capability

WAN routing

Proxy ( Access control mechanism I can say )

I heard of few Juniper devices which can Firewall,router & proxy. All 1 in box. But i prefer Cisco appliance. Any suggestion with technical positive and negative points ?

Thank you,


Amey Abhyankar.

I have this problem too.

Nokia/CP and Pix can not function as a proxy

Nokia/CP, Pix/ASA and Juniper can not function

as a AAA server.

If you are looking for an ALL in 1 solution,

I would suggest that you go with Linux

firewall. The linux can function as the


AAA Server = Freeware Tacacs+ and FreeRadius (I have it running right now and it is working great)

proxy server = squid (i've it running right now)

firewall = ip masquerading with iptables (i've it running at the moment)

WAN routing = I've not tried but I think gen2

can do this. By that, I mean you can

terminate WAN connection such as T-1, Frame

relay to the linux box itself.

DHCP Server = dhcpd.conf will do the trick

As far as support for the linux firewall/

AAA/DHCP/WAN routing/Proxy, that's a separate
