I’m installing a Cisco 678 for a DSL connection. I’m hoping that the Cisco router will allow me to easily do some thing I’m not able to do with my current router. The first part below shows my current router’s configuration and the second part is the ideal configuration with the Cisco. I need some help with second part. I’m familiar with the command line interface on the Cisco and prefer to configure the router this way. I need some help with exact commands for the router to achieve the configuration I want.
1. I have 3 servers with static IP addresses from a pool of 8 given from my ISP
2. I have 10 workstations with internal IP addresses manually assigned to each workstation and they are able to access the Internet but no one is able to access them from the outside.
Ideal configuration with the Cisco 678:
1. Keep the 3 servers with static IP addresses
2. Have the 10 workstations and any future workstations use DHCP to obtain an internal IP address to access the Internet
I have been able to configure the Cisco 678 to have static IP addresses or to do just DHCP with internal IP address but NOT Both.
