1 edit |  CISCO uBR904
Does any one that uses insight bb, have a working Cisco uBR904 installed? I spent quit a bit of time with insight support to get it to work until we found out a feature called 'cable-modem dhcp-proxy nat' was not supported by this model.
I will not get into the specifics now but if anyone is interested please post. I am interested in a work around for this DHCP shortcoming. |

1 edit | I don't recall the 904 working but I know the 924 works. I am not aware of a difference that would cause it not to work. Is the IOS updated? I don't know if this will help at all. »www.cisco.com/warp/public/109/ca···at-confs
I also found this.
Note: If you are using uBR904 and want to perform NAT, then you have to request a static IP address from the MSO. Once you have the static IP address, you can configure NAT on uBR904 by:
creating a loopback interface
using a Ethernet secondary interface
You could get a sticky IP and try it. Here is a link to the instructions.

| Thank you, but I have seen this and i don't want to pay for the sticky ip. I do know the difference between the 904 and the 924 is the support of IOS 12.2(t) which supports the cable-modem dhcp-proxy nat command. this allows for DHCP and NAT, to work on the 'outside interface' and for the uBR to pass through a dhcp address to the interface on the 'inside'. |

What IOS ver are you running? I think the 904 is at end of life...I have CCO access and if you dont I can check in the morning for the latest IOS ver and help you out if I can... |

Lexington, KY | That is the best news i have heard yet. No I do not have CCO, and I think my current ver. is 12.1(6). They recomend ver. 12.2(t) or higher, but I only saw that for the uBR924. which are different HW platforms. Thanks |

Ok here is the last and latest for the 900 series...
File name Min. Memory
(MB) Min. Flash
(MB) Date Released
ubr900-k1y5-mz.121-22c.bin 8 4 13-APR-2004
There is no 12.2 IOS for that model 
I dont think that this 12.1 will support the IOS command you need...however you still might be able to NAT...they recommend a static IP which you dont want to get BUT you can still enter your current DHCP'd IP etc. info from insight as a static into the router, which atleast will give you something to test...the down side is that when insight changes your DHCP'd IP you would need to get that info and again enter in the router...
Post some router info...

| This config was built with the assumption the cable-modem dhcp-proxy nat command was going to work.
