1841 PPPOE - Static ip configuration issues - No Connectivity to ISP

Melvinb1981
Level 1
Level 1

Good Day, 

 

Hoping for assistance,

 

I have a Cisco 1841 Router that i want to connect up to my ISP modem. (They requested my Mac Address of the original Router Not Cisco - I have however cloned the Mac Address to my Cisco router trying to rule that out as an issue - Wanting to use this instead of the ISP provided router.) 

I have also tried using both chap and pap , running debug commands this should allow some sort of indication if its an authentication issue but no display of errors. 

 

I have not configured any nat configurations as of yet im literally trying to ping any address within the console port

 

What has been provided from the ISP side is the following:

 

  • Static IP Address
  • Subnet Mask
  • Gateway
  • DNS Settings
  • PPPOE Username & Password

Hello,

 

The Fibre cables goes to the white box, RJ45 then to the Calix Box. Wan Port.

I cloned the MAC-Address of the Calix device and applied to int fas 0/0 port (1841 cisco) in the hope that would bypass any security issue with having to be specific to ISP hardware 

Yes the ISP Modem and Router are two different devices. 

I want to make use of my own personal device the Cisco 1841 Router

 

Hello

ip tcp adjust-mss 1452

ip route 0.0.0.0 0.0.0.0 *.*.*.*<ISP next hop
