Main Topics
Browse All TopicsHi,
I have started a home lab and have a Cisco 806 router with IOS 12.2 IP F/W Plus installed on it. I am trying to set up the 806 to be my gateway between my home network and my cable modem. I have set up nat and have that working properly, and I have tried RIP v2 running between the 806 and Linksys, which works ok, my problem is that I can't pull a DHCP IP address from my ISP from my e1 int to save my life, I can get an ip on my linksys off the cable modem and direct into my PC just fine but when I try it on my 806 no matter what I try it just wont take an IP off my cable modem, I know it has to be something in my config, because my modem works fine everywhere else, if you guys could take a look at my config and help me out I would appreciate it - THANKS!!!

I was able to get an IP on my 806 off my linksys, thru DHCP after I removed the "ip verify unicast reverse-path" command , but still unable to get one from my ISP thru my cable modem, even though I can get one on my linksys and direct to my PC off the same modem, kinda weird, maybe Cisco uses a different port # for DHCP requests and my ISP may not recognize it or be blocking it, thanks for the help though Irmoore
You need to call the cable company and tell them you are changing to a new PC and need to have the MAC address cleared from the cable modem. To prevent people from sharing their cable modems amongst multiple computers, the cable modem remeber the MAC address of the first system (be it PC or broadband router) and will not communicated with other devices.
You should be able to just shutdown the cable modem for about 5 minutes to release the mac address from the cable provider. This is the case 90% of the time. On the second part of your request see if this will help:
int e1
mac-address XXXX.XXXX.XXXX
ip addr dhcp client-id XXXX.XXXX.XXXX hostname COMPUTERNAME

Have you tried it without this line?
Also, reboot the modem after disconnecting the Linksys.
