Do I require a router if I have a single IP, no on-line servers and a CISCO PIX Firewall?

Hello experts

I am just trying to finalize on the network setup for a 20 - 40 person office. I have put together all the internals but have one remaining question for external access.

The criteria to satisfy and setup information is as follows:

1. No on-line servers, mail will be popped from external provider and web-site will be hosted externally
2. We will have a single routable IP address
3. Require VPN access for mobile users
4. CISCO PIX firewall

Now my question as the title implies is, if I have only a single IP address do I need to worry about a router as well as the CISCO PIX or can the PIX take care of all the routing required for my network. That being internet access for users, mail retrieval and VPN access for mobile users.

I am thinking about the setup below:

Internet ----> CISCO PIX ---> Internal switch ----> servers and workstations

Or do I need

Internet ----> CISCO PIX ----> router ----> internal switch ---> servers and workstations

Which one of the above would be best suited to a single IP? Or is there another option that I need to consider?

If taking option one, to get intetnet access would I need to set up workstations etc to point to the PIX's internal network IP as the gateway address?

Now if I was going to received additional IP addresses would I then require the use of a router or can the PIX handle more than one routable address for my network?

Many many thanks in advance
Steve

Hi Steve_Waters,

Please remember that the connection most often looks like this:

Internet -> Router -> Firewall -> Switch -> LAN

It all depends on the connection you will be getting from your ISP.  If they provide you with a direct Ethernet or Fiber connection you will be able to do away with the router, or if it is some sort of bridged connection that does not require a router.  Again, if you Pix has a Wan port that conforms to your Telco services, you may also not need a router as the Pix will be the router.

M

Ok

Thanks for that.

So it all really depends on the connection type my telco gives as to whether I require router or not.

Does this still apply if I have multiple IP addresses?
