I have two machines with private addresses hosting web sites behind one public IP address. One is a company site(IIS4 port80) and the other experimental(IIS5 port81) that crashes 3-4 times a day, so I don't want to move either site to the other machine and let IIS read a header. The experimental machine is being run on port 81 and this is a problem with some clients IT dept's won't allow access.
1. Is there a single router that will allow multiple-NAT translation so both machines can run on port 80 through one router? (I.e., will the Cisco 806 do this??)
2. Would assigning a second public address help (we have 4 according to our ISP)? I know both would not run behind the router/firewall (current problem), only the coporate site. So would that mean Internet-Switch-Router/firewall-server for the corporate and Internet-Switch-Server for the experimental(port81) skipping the firewall?
3. How quickly do you think hackers will trash the thing if just sitting on an direct address to the internet? It is IIS.
