I have an ADSL model connected to the Internet. I also have a Cisco 2514 router that I would like to connect to the ADSL modem to provide Internet to the internal network.
I erased the startup-config on the 2514 so as to configure it from scratch. The 2514 router is running IOS 11.00. I assigned IP addresses to the two Ethernet ports on the 2514. One Ethernet port on the 2514 (assigned IP address of 192.168.0.1 and mask of 255.255.255.0) is connected to a hub and the other port to the ADSL modem (assigned IP address of xxx.xxx.xxx.206 and mask of 255.255.255.252 where xxx is a number). The modem IP address is xxx.xxx.xxx.205. I could ping the two Ethernet port from a PC connected to the hub. However, I was unable to ping the ADSL modem from the PC but I could ping the Modem from a telnet session on the 2514. I could achieve what I wanted to do using Microsoft W2K with Internet sharing enabled.
I am not sure what to do next. Does RIP needs to be enabled? Do I have to do anything with the static route table. Would you be able to give detail instruction.
Thanks in advance for your help.
