Hi guys,

I am trying to access my home network from outside by setting up a VPN on my Mac to access my PC at home. I can access the PC remotely using Microsoft Remote Desktop if I am directly connected to the network without a VPN. I can also sleep and wake the PC up too.

The question is, when I try to replicate this using VPN, I can only access my PC and make it sleep, but I can’t use WoL. I correctly set up the VPN using no-ip dyndns with Cisco IPSec. My IP address has a different subnet than the local network, and the nature of WoL being what it is, I tried to add the rule of port forwarding. However, when I tried to check my port using https://www.portchecktool.com/, port 9 could not be opened.

I deactivated the firewall on both the PC and router, could this be that Sunrise may have blocked port 9?

Or is there a way that I can use WoL from a different subnet IP on a VPN?

Thanks, guys,

VPN typically doesn’t forward WoL packets, this is per design. You’d need to initiate the WoL packet ideally by a device within your internal network.

pato I’ve gathered that, but I wondered if there is a way around this.
Otherwise, it seems a bit illogical to me that people would always leave their PC on 24/7 for access.
Do you have any other suggestions? I read a couple on making a Rasberry Pi, something which I want to avoid.

kyuk Some NAS should offer such a function, like Synology or QNAP, but I never used it. They also typically offer a VPN gateway and everything.

So there is nothing I can do to overcome the issue without buying extra equipment or hardware?

None that I know of at least.
