QUESTION
I have an EC2 (t2.micro) on aws as a test server and I am trying to create a simple PPTP VPN server with internet connection. I followed some tutorials and did as follow:
- Add roles and feature (Remote Access)
- Add a user in computer management with 'Allow access' option enabled.
- Enabled and configured 'Routing and Remote Access' security MS-CHAP v2, and enabled IPv4 forwarding with range between 192.168.10.10-192.168.10.19
- In 'Routing and Remote Access' Under IPv4-NAT created public Ethernet interface with NAT enabled.
- In the server allow access for port 1723 (TCP Inbound rule).
- On amazon console created allow access TCP inbound rule for port 1723.
Now when I try to connect to my server from my PC using PPTP connection (with MS-CHAP v2 and optional encryption) it shows the following error after a while:
AM I missing a step or something configuration?

QUESTION
I'm trying to make a Node.JS proxy for FAST protocol over UDP multicast (PPTP connection).
...ANSWER
Answered 2020-Sep-11 at 13:09Looks like i have found the source of problem, so does alternate resolution.
It's not enough just to join multicast group, it's also required to enable source filtering of packets:
install and start smcroute daemon: apt-get install smcroute smcroute -d
join multicast group with enabled filtering (source IP required) smcroute -j ppp0 91.203.253.235 239.195.9.9
then application starts to get multicast packets: tcpdump -i ppp0 -s 65534 host 239.195.9.9
- Additional info: while i was searching for answer i've found UDP to TCP proxy tool: https://github.com/MarkoPaul0/DatagramTunneler (which solves multicast join params shortage, as i couldn't find multicast join param for source ip filter in Node.JS)
QUESTION
The code for my scanner is below. If I decide to check if only port 2220 is open on 176.9.9.172, it tells me that it is. However, when I run option 0 to check ALL the ports up to 10000, it only registers that port 22 and port 80 are open. It's multi-threaded and runs up to 4 threads at a time. It waits for the 4 threads to complete and then deletes them and resets the vector of threads to reduce memory issues. I'm not sure what's causing the problem.
UPDATE - I added a section of code after myNetworkSocket = socket(AF_INET, SOCK_STREAM, 0);
in the TestPortConnection() function, and as I ran it, I found that the socket creation failed after I scanned ports 1 - 1023. I realized that I forgot to close the ports if they failed to connect in some situations. I inserted the code to close them, and it works now!

QUESTION
I am establishing PPTP connection to the remote server programmatically using RAS api in Windows. The problem is that when server disconnects (for example server stopped) windows automatically prompts user to redial (see screenshot), I don't want this prompt to be shown since my app handles everything by itself but couldn't find any options in RASENTRY to do so. This behavior occurs only on Windows 7, how this could be solved?
...ANSWER
Answered 2020-May-05 at 10:25The problem was the RASEO2_ReconnectIfDropped option that I used for creating a connection. After removing it - prompt does not appear.

I have a powershell script where I can add an VPN to the local computer. It prompts for the users credentials and after that it creates the VPN connection and adds the credentials. When I try this on my own computer it works perfectly fine but when I try this on another computer it gives an error saying Set-VpnConnectionUsernamePassword isn't a command.
Does anyone know what causes this or how to fix this.
