BTW, can you turn off the radio you implanted in my tooth while I was sleeping. The buzzing is driving me nuts.

...is it remote (on a separate LAN) from your home?

If you are using a software product that you install on both computers that makes the connection, I have no idea. You might try asking the folks at the support line/page of the product.

I have used a netgear router which worked well and kept a log of some access details. Maybe your router or gateway device keeps a log. Get the model number and google up a manual.

I currently use a vpn when I need to LAN presence. I have a network attached storage device that offers a vpn app. This is not a public vpn service that masks IP addresses. It operates the same way but I use the connection to have a simulated LAN presence. Many offices have a vpn setup for employees who are on the road or just working from home.

If you're using a vpn to connect, their may be a log kept by the hosting software.

The last and somewhat risky method that I've used is port forwarding port 3389 from the router/gateway to the LAN IP of the computer locate remotely from you. You can then use the windows remote desktop function to connect. Generally the computer you connect to needs to have the pro version of windows. I say it's risky because it kind of negates any firewall function of your router and puts your computer on the public internet. I've done it for limited times by changing the port forwarding to an unused IP on the LAN as soon as I'm done. Years ago when I checked the router logs there were access attempts every 5 or 10 minutes at port 3389.

If none of this sounds like your method can you give me more info on how you're connecting?
