Network Firewall Advice jgoodale 11-21-2005

I have two servers that I want to place in a collocated facility but I
need to select a device (a managed switch I believe) to place in front
of the servers to protect them from hacking attempts and route the
appropriate traffic to the right machines based on IP and port.

I only need 4 Lan ports and 1 wan port.

The setup will be something like the following:

Live Server (Win OS)
Dev Server (Win OS)

Many Public IP's to the router through one ethernet cable.

I need to route the traffic through the device based on port and IP
combined.

This device would also need to be very stable and have good
connectivity on the local network (gigabit) since the servers transfer
a lot of data amongst each other.

Simplicity of interface is also going to be a concern since I'm a
programmer and not a networking guru. I can handle setting up routing
tables on a very basic level but anything CISCO is going to be out.

Cost is also another factor. My spending range for this device should
not exceed $400.00.

I would prefer a smaller device so that I don't get charged for space
from the co-lo company (not something that is rack mountable).

Thanks for your help!

James

Not going to want much protection for your network/nodes then.

For that range of price you can't get much that would provide all that
you want.

Very few "managed switch" will "protect from hacking attempts"

Very few "managed switch" can do Network Address Translation (NAT).
Some will do Policy Based Routing, but not until you are into the
"Layer 3" or "Multilayer" switch range.

You are going to have a hard time finding a plain managed Layer 2
gigabit switch for $US400. With the other features you want, I think
your only option in that price range would be to build your own from
donated parts and could your time in programming and testing it
as being "free".
