One of my clients needed a site-to-site VPN. Searching online I found some sites that were very helpful.  I decided to configure it using tun rather than tap. The difference between tun and tap is tun can tunnel traffic between 2 different subnets where tap you have to use the same subnet on both ends (they call this bridge). Both ends have different subnets and I did not want to change them. The other reason is tap is slower because it sends more traffic over the VPN then tun.

Now the first site describes on how to setup the initial OpenVPN configuration. Following the instructions on this site of Part 1 and Part 2 got me the initial connection. If this is the first time setting up an OpenVPN on a Tomato router I suggest that you DON’T check the box Start with WAN in case you make a mistake. I did in the certificate and it made the router none functional. Because I specified start with WAN even a reboot failed to work. I had to reset my router. Start with out start with WAN. Once the initial connection works then you can go back in to Tomato and check the Start with WAN. The instructions setup using tap so if you want to make a tun connection then only follow the certificate part (Part 1 and Part 2 for inserting Certs into Routers) where you download the OpenVPN, install and make the certificates. One thing it did not specify is when you run the setup for installing the OpenVPN make sure you check all the boxes. Make sure you check the OpenVPN RSA Certificate Management Scripts or you won’t be able to run the scripts in Part 1. When it says the Common Name make sure you write it down. You will need this later. So if you follow the instructions correctly in creating the certificates and you put them in the server and client Tomato routers.

After the certificates Keys are entered into the Router then here is the instructions for tun to work so that you can ping both client to server AND server to client.

On the Server Router here is my configuration:


Now the Advanced

For my example this is my configuration:

Server subnet

Client subnet

Common Name used in the certificate creation COMMON-VPN-NAME

How this works is the push and route commands in the Custom Configuration allows the client side to ping or connect to the server side.

For the server side to ping or connect to the client side you have to specify Manage Client-Specific Options. Allow Only These Clients checked and then add the client Subnet. You have to specify Enable and you have to specify Push. Make sure the Common Name is the same as the Common Name used in creating the Certs/Keys or it won’t work.You then need to restart the VPN (Stop Now and then Start Now) on both Server and Client.

One thing I found out in another forum is when I configured the Client part to allow Ping connection from the Server to the Client side I could only ping the client router (10.0.0.X) I could not ping the Windows PCs. If you want to ping you have to disable the firewall on the Windows PC. Connection will work fine with the firewall enabled it just won’t respond to pings outside the Windows PC’s normal subnet.

Looking online I came across a few forums with similar issues. I have compiled a few solutions that might fix the issue:

Computer goes to sleep automatically after a short time.

Solution 1:

Finally found the solution,just in time too because I swear I was about to go insane.

Right click on desktop > Power and sleep > Additional power settings > Choose when to turn off the display > Change advanced power settings > Restore plan defaults

I don’t know why but this completely got rid of the issue and I was then able to make the settings whatever I wanted.

Solution 2:

  1. Click on the windows icon
    2. Type regedit
    3. Right-click on regedit icon, click Run as administrator
    4. Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\PowerSettings\238C9FA8-0AAD-41ED-83F4-97BE242C8F20\7bc4a2f9-d8fc-4469-b07b-33eb785aaca0
    5. Double click on Attributes
    6. Enter number 2.
    7. Go to Advanced power settings (click on Windows button, write power options, click on Power Options, in the selected plan click on the Change plan settings, click on the Change advanced power settings).
    8. Click on the Change settings that are currently unavailable
    9. Click Sleep, then System unattended sleep timeout, then change these settings from 2 Minutes to 20 for example.
    That’s it!

Solution 3:

i was have the same problem,

when i changed,

Contol panel -> Hardware and Sound -> Power Options
Select from left panel “What the power buttons do”
And make all button options, “Do nothing”

the problem solved for me

Note: I am using notebook with external screen, my notebook’s screen always closed, but windows 10 doesn’t know

Solution 4:

I have found a workaround using a downloaded no sleep program that moves the mouse one pixel back and forth every thirty seconds or so. Imperceptible to the eye, but enough to make the computer still think it is in use so that it will not sleep.[/QUOTE]
I agree is it silly that this problem hasn’t been corrected yet.
Do you have a link to the no sleep program you use? I need to stop my computer from shutting down b/c I take tests for school online, and if it shuts down while I go to the restroom.. then test is final, completed or not.



Solution 5:

This from another forum fixed this issue for me.

Got to:


Edit each of the sub-keys. Each corresponds to one of the power plans. If you choose ACSettings (Decimal value is 3600 seconds for 1 hour) you are choosing a behavior for when the machine is plugged in, DCSettings are for battery power.

Solution 6:

I had the same problem and I figured out an easier fix. select all your power setting that you want. then I went into screen saver menu, mine was set to blank. I selected another one then reselected blank and click apply. That is all it took.oh and by the way, my power settings, on battery and plugged in, were set to 15 minutes each, I switched them to 30. after that do screen saver, and apply settings. it should work. I was also on windows 7 and was upgraded to 10.

Migrated a client to a new Exchange 2010. One of the clients still using POP3. I enable the MS Exchange POP3 service. Made sure all settings are OK in client configuration but still would not work. I have it set to plain text (I know security risk) but when I telnet to the server on port 110 that worked but when I entered USER username it gave error:

POP3 ERR Command is not valid in this state

Found this article that fixed the issue

Basically had to do the following:

 1. Log into your Exchange 2010 CAS server
 2. Open the Exchange Management Shell
 3. Issue command Set-PopSettings -LoginType PlainTextLogin
 4. Restart the Exchange POP Service

Seems there is an issue with Adobe Reader DC and the new Windows 10 Anniversary. Some people are complaining that some PDFs when printing causes streaks where the lettering is.

Read this Forum. Seems Adobe has still not fixed the issue after 2 months!

2 Solutions so far is print as an image (Not the ideal way but it works). Others said Foxit Reader seems to work. I have not tested this yet so I can’t say if it will work.

Adobe fix your bugs!!
