Hello All. I just got my hands on a Cisco 837 router and was wondering if I could get assistance in configuring the device to work with my cable internet account. I need assistance in understanding how to set the E1 (wan connection to assign it self an IP address from my cable modem). I would also like to ask for assistance in setting up dhcp serving with the understanding the WAN connection is assigned dynamically.
I have my CCNA, however I do not have any experince with these router/switch combo devices. Any assistance would greatly be appreciated.

Hello Vinnie,
when you say ´E1 WAN Coonection´, I assume you are talking about PPPoE ?
Here is a basic PPPoE sample config which should work on your 837 (obviously you have to modify the IP addresses and username/password combinations).
Can you try to configure this on your router ? Let me know if you run into trouble...

Thank you GP for your assistance. However, is there a way for any ports on the 837 to gain its ip address through DHCP from the ISP? The ISP is a cable provider and does not use PPPoE. The Cable modem dishes out a IP address to the connected device via DHCP. I was just wondering if it was possible to set the 837 as a gateway type router. If not, I do understand...the product was free to me so I was just trying to find some use for it.
