ARN and DHCP help

[OmegaVTX]

Nortel is not cutting it... Please help.

Logical layout:
DHCP server-BCN-ISDN-ARN-Client

I have an ARN at remote site and I need to setup DHCP forwarding so that my client can get DHCP.

I was told it is my version, but this router was in the field at another location working just fine not to long ago.

In Site Manager:

I do have BOOTP enabled on my ethernet interface, but under protocols -> IP -> the BOOTP option is grayed out.

I was also told by nortel that if I set the Prefered Server on my BCN that it would work.. I did and get ??? then my IPs for my outside ISDN interface going to the remote site and my DHCP server address (as I entered them).

If this is the only thing I need to do, dont see how since the client on the far side of the ARN is making the DCHP request, why do I have 3 ?'s...

Any guidence will be appreciated.

The bootp option shouldn't be grayed out as long as the protocol is installed on the interfaces. Typically I put the bootp protocol on both interfaces (LAN and WAN). Under the BOOTP relay agent interface table, click on Forward I/F, enter your input IP address (where the request comes from), then the output address (where the request gets forwarded to). Set the passthrough mode to BOOTP/DHCP, and you should be all set.

On the ARN, the "input" address is the LAN, output is the WAN. On the BCN, the input address is the WAN and output is LAN.

Hope this helps.

Thanks!

FYI I had to remove BOOTP from my interface and re-add it to get it back???

It's possible. It might depend on whether you made the initial changes in dynamic mode or remote. Sometimes just kicking them around a bit wakes them up.
