Does anybody have any ideas why wake on lan over internet doesn't work with my DGL-5500 and my Rampage IV extreme mobo custom setup. I have configured everything properly as far as I can tell. I can wake the computer with a magic packet (from off) over LAN IP, and also over internet, but only for about five minutes after the computer has been powered down. From what I've read, I'm guessing the router drops it from it's cache after 5 minutes. I have my computer assigned an ip in the router setup pages, but this did not solve the problem.
Is it possibly the arp cache that is reset on the router? As a note, wake on LAN over internal network IP (ie. the 192..., works no matter how long the computer has been off), but wake on wan does not work after about 5 minutes or so of being powered off. Any ideas or suggestions would be greatly appreciated.
