WOL over VPN for two devices

[Andreas Werner]

Hi,

I want to use WOL (Wake-on-Lan) over VPN, but I didn't manage it yet. It's no option either to use WOW (Wake-over-WAN) using a port forwarding, or using a SSH script.

I have tried:
* Port forwarding from WAN: Failed due to the fact, that a specific port can only forwarded to one maschine, not more. I have to do an implementation accessing two devices.
* Using an IP range for VPN within the same network as used for LAN, but outside the DHCP range. Failed due to the fact that there is an error displayed all times that networks "overlaps".
* I found no option to define broadcast routes between two subnets (Lan & VPN).
* I found no option to set up DHCP options for VPN, like range or fixed IPs.

Still implemented:
* VPN is working fine, secured by passphrase and certificate, I can access the running devices within LAN from VPN

Hardware used:
ASUS RT-N66U with Merlin latest build.

Any suggestions??

Thanks

Hi,
in order to have WOW (wake-on-wan) work, you must issue an arp command (at SSH/telnet level) to make the ip address static in the arp table.
synatx is : arp -s ipaddr macaddr

P.S. of course, you choose which external port to use and make a port fwd to the internal ip on port 9 (usually used for wol)

As I wrote port forwarding from WAN to LAN is not the goal, it has to be implemented using VPN only.

Your tip was very helpful, thanks therefor, I implemented a static arp table entry using this thread:

And now WOL over VPN is working, even after robooting the device.
