MS Proxy Server 2.0 question.

By pbutler ·
I?m in the process of installing a router, a firewall, and a proxy server. I?ve configured the proxy servers LAT to include all internal IP addresses. I've also added a external NIC with an excluded IP address. I know Proxy requires an external IPaddress which should be the interface to my gateway. However, I?m confused as to how I can route my users through my proxy?s external NIC through the firewall. The firewall has an internal IP address and an external IP address. The router and the firewall are configured and ready to go. I figure there must be way to route my users through the proxy and then through the firewall without having to hook my firewall directly to the proxy. I only have two Ethernet ports on my firewall one for the external and one for the internal. Any suggestions would be appreciated.

I think you must exclude from the LAT the NIC which connect to the firewall. All client must view external connections by the internal NIC of the proxy. The external nic which connect the firewall must have access to the dns for internet resolution.

You need to set up a DMZ. The external NIC of the proxy is in the DMZ and the internal NIC of the firewall is in the DMZ. The firewall is instructed to pass traffic coming into the organization to the external NIC of the proxy and to accept traffic heading out of the organization only from the external NIC of the proxy. An HTTP server would also go in the DMZ and the firewall would be configured accordingly. Don't forget to open only the ports you need to get the job done.

You need two NIC in your Proxy Server. This is not clear to me from your question. Your LAT should include only the IPs of the systems on your internal network. The outside NIC will have a masquered ip or a routable ip depending on how you setup your firewall. The Gateway of the outside NIC will be the ip of your firewall. Run the proxy client on all systems on your inside network.

Attach your inside NIC to a HUB or Switch with the rest of your systems.

If your firewall is setup to pass only the ports you want comming from your router, you should be able to see the web and receive e-mail.
