need ddns proxy for remote scripting or other solution

[Duane Cox]

Hello List:
First let me briefly explain my scenario to give a better understanding of what I need, maybe somebody has a better idea.
We deliver FTTH (voice/video/data) using hardware from wave7optics.
The CLI in their operating system is also configurable via SNMP.

The issue...
Each device has an interface called a CHANNEL (6 total) that can hold 16 customers each, so a total of 96 customers per device.
Each interface channel can have a max of 32 rate limiters, but I use the first 10 for QoS for VoIP and IGMP, etc. and the last 32nd is a "DEFAULT".  But this still leaves me with 16 rate limiters to use for each customer, plus some.

I have a pool of 32 addresses associated with each channel.  So I have more IPs than can actually be used, and I have more IPs than I do rate limiters to use on them.

So what I am looking for is some way the DHCP server, through a custom script or program, to update my device via SNMP with the IP address that the customer is currently using.  I can create the script, I just need a way to get DHCPd to act on it.

One solution I thought of was intercepting the DDNS output of DHCPd.  But I don't know if this is possible, or if any of you DHCPd admins have a better idea?

Thanks,
Duane Cox
