Westell 2200 DSL Modem with a Cisco PIX 506e
Posted on 2006-04-23
Hello EE Gurus
I am working with a client to set up a Pix 506e. They have Verizon business DSL and currently use the ISP provided Westell 2200 DSL router as the DNS/DHCP host for all the clients on the local LAN. I have set up a Wndows 2003 server with DHCP/DNS services for the local hosta and hope to configure the PIX in front of the DSL router to firewall the internal LAN including set up of a point to point VPN to another site.
How would I go about the config? Looking at the the documentation it seems there are 2 choices, setup a Public LAN with IP pass-through or setting up port forwarding of traffic to an internal host.
I have asked the client to upgrade their service to obtain a static IP from Verizon for the public interface of the PIX. I just need the Westell to route all in-coming and out-going traffic to the outside interface of the PIX behind it. Any information on how to accomplish this would be helpful. Thank you in advance for your advice and time on this issue.
