Excuse me please, but this is neither helpful nor polite :smileymad: One would think that any customer intelligent enough to pose such a question also is intelligent enough to figure out the "less complicated" method.
This just wasn't the question. The question was how you can wake linkstation via internet. Your customers deserve that you at least think about that option for a moment before dumping it. Sure, wake-on-lan does not equal wake-on-wan, but I'm pretty sure it's not impossible.
What about using a VPN-tunnel? This way, your PC virtually appears to be part of your lan despite being connected only via internet. Shouldn't it be possible to send wake-on-lan orders through the tunnel repeatedly to do the job?
Best regards.
