Hello SBS and Cisco Experts,
I have a small network that consists of 1 Microsoft SBS 2003 and 10 workstations. We have one static IP from our ISP (71.39.164.xx). The DSL modem NATs that address to 192.168.0.1. Our SBS server has two NICs. The external NIC has an address of 192.168.0.2. The internal NIC has an address of 184.108.40.206. Each workstation is assigned an address via DHCP. The gateway for each workstation is 192.168.16.2 (the internal NIC on the server). So basically what is happening is all internet traffic is being routed through the server.
Our IP address keeps showing up on a CBL blacklist. I have run scan after scan on the server and everything comes back clean. I'm as confident as I can me that the issue is not the server itself. What I want to do is the following:
1. Purchase a block of static IP addresses from the ISP
2. Purchase a Cisco ASA 5505
3. Configure the ASA so that one external IP is used for the server and a different external IP is used for the workstations.
My question is can the ASA do this? I think it can, but want to be sure before I spend any money.
