Crafting Magic: Exciting Materials for Moms to Create Memorable Moments with their Children

Network Conditions

The current office network environment is:

– 3 routers : each public IP ( 3 ips )
– 2-3 computers / lapop per 1 router
– All routers are connected to the 1 st NAS
– the1st NAS is automatically backed up to the 2nd NAS

Since we cannot use the same IP / same computer for work, there are three KT modems for public IP set up, and an iptime router is installed for each KT modem, so that multiple desktops (PCs) and laptops are connected.

In this environment, we have the inconvenience of having to move around when we have to access different computers for work.

Also, there are times when we have to work outside. (In this case, you need to turn on the computer to be able to connect externally.)

Windows Remote Desktop on Desktop PC

If you do a Google search, you will find a lot of setup methods.

There are essential setting elements,

– Enable Wake on Lan (WOL) option in Advance menu in most desktop CMOS BIOS

– Enable the DDNS function of the router

– Connect the desktop you want to use in the WOL of the router

– Changed the default port 3389 of Windows Remote Desktop/RDP to another port for security.

If you do this, it is very easy to remotely boot your PC and access the Windows Remote Desktop.

– After running Windows Remote Desktop in the Windows search bar, enter the DDNS address entered above to connect.

Most laptops’ CMOS does not support WOL or boot on power-on.

So, I tried various programs/settings through Googling, but I couldn’t use it.

However, after much effort, I found a solution.

– The laptop should always have a wired LAN cable and power cable connected.

– Wireless Internet cannot be used because it cannot send packet signals.

– It is meaningless because it cannot be used for several hours when used with batteries.

– Basic DDNS and WOL settings are made only on the router like the desktop above.

– Control panel of the laptop – Power Options – Set ‘Do not use sleep mode when using power’ as shown below

– Device manager – Network adapter – Power management of the LAN card in use
(Check after selecting all 3 locations)

– Although it is different for each notebook manufacturer, change the WOL Magic Packet / WOL pattern matching value to ‘Enable’.

– Change the value of ‘Shutdown Wake Up’ at the bottom of the same screen to ‘Enabled’

– The reason for this setting is that even when the power is turned off, the light on the LAN port on the back of the desktop blinks and the signal is transmitted, but the laptop has that setting turned off, so you have to set it to Enabled for remote booting.

– All settings are now complete.

– If you want to use remote boot laptops that do not have WOL option in CMOS,

Instead of shutting down the power, it is possible to remotely boot the laptop after putting it into sleep mode.So, I am reducing electricity bills by remotely shutting down or saving power in the office or outside, and I am using it after remote booting with a smartphone conveniently anytime, anywhere.

After installing the Android Google Market – iptime wol app on the iptime router I am using,

– PC is remotely booted with iptime wol app after complete power down

– The laptop is being used by remote booting with the iptime wol app in sleep mode.

More secure security settings when using Windows Remote Desktop

I don’t think there will be any major security problems when using it after remote setting as above, but let me explain how to use it more safely.

– The best thing is the VPN supported by the router – If you allow access only from a specific IP, you are perfectly secure.

– As a result of using it, it is too cumbersome and cumbersome, so I use it as follows.

– Windows – Run gpedit.msc

– Set the ‘Account Lock Policy – Account Lock Threshold’ to ‘Locks the window itself for 30 minutes when login fails 5 times.

– I set it to 5, but you can adjust the number to suit your convenience.

– Most hacks are automatic programs and random login attempts, so you can set it to 5 to 10 times.
