WOL is unfortunately terribly deficient in that the spec. never envisioned the possibility of a need for wake on WAN. Bottom line, it's a non-routeable layer 2 protocol. Your choices boil down to the helper address nightmare you describe or proxy servers on every subnet. Owen On Dec 13, 2010, at 8:08 AM, Berry Mobley wrote:
Hello...
I'm trying to get a handle on implementation of wake-on-lan in an enterprise environment. Cisco gear, lots of subnets. I've made it work with directed broadcasts, but I'd really rather not have 40 or 50 'ip helper-address x.x.x.bcastaddr' statements on the vlans with the SMS servers.
Are there any enterprises that are doing this for large (100+) numbers of subnets? I can't find a single example anywhere with more than 2 networks.
I've searched the Cisco-NSP archives as well with no luck, but maybe I didn't go back far enough.
Thanks for any help you can provide.
