I will install and configure a VPN server in China for $ 80

I will install and configure a VPN server in China

I will install the VPN server using Openvpn, Softether, L2TP, PPPTP, SSTP, IPSEC and Pritunl.
This VPN configuration is for remote VPN using VPS or dedicated server. You must select a protocol, there will be an additional charge if you choose more than one VPN protocol.

Free to request port. I can work through remote desktop or SSH Connect

Contact me before for a complex scenario like installing a VPN server in your home / office

networks: connection to NAS through reverse proxy in external VPN

Being behind a 4G-ISP with CGNAT, I cannot connect to my QNAP 269L NAS from the Internet.
I have configured a Raspberry 3B + as a VPN server in a place of friends, with a fast Internet connection.
Could some of you, brilliant people, give me step-by-step instructions on how to configure this, so that I can connect to my NAS from the Internet, through this OpenVPN server (piVPN)?
If I have understood the days in Google well, I need to configure the reverse proxy and some type of port forwarding on the piVPN server, but I have not been able to make anything work.
Thank you very much in advance, Mitscha, Denmark

networks – qemu – second network interface to open vpn tap

I have a Linux host that runs a Windows vm with qemu. As a network configuration, I have an eno1 interface that connects the linux host to the internet, a tap_inet for qemu for internet access and br_inet bridge that links those two. With this configuration and the qemu command with a network card
(qemu -netdev tap, ifname = tap_inet, id = n1 -device e1000, netdev = n1, mac = 00.00.00.00.00.04 …)
everything works find and in the vm I get an address from the router.

The goal was to connect a network card to qemu to interact with an openvpn network. On the Linux host I have an openvpn client that works with the tap0 network adapter. But when starting qemu with two network cards
qemu -netdev tap, ifname = tap_inet, id = n1 -device e1000, netdev = n1, mac = 00.00.00.00.00.04 -netdev tap, ifname = tap_ovpn, id = n2 -device e1000, netdev = n2, mac = 00.00. 00.00.00.08 …)
The tap_ovpn that I intended to join with tap0 is automatically bridged with br_inet, which I confirmed with brctl show.

According to https://www.qemu.org/2018/05/31/nic-parameter/ this should not happen. Networks should not be bridged as with the old -nic command. But all network interfaces created by qemu are automatically assigned to the br_inet bridge.

I think the openvpn configuration is correct, on the Linux server I have a tap0 interface with a static ip 172.16.17.2 as a client on my openvpn network. In the client-specific configuration file, I added iroute 172.16.17.3 255.255.255.255 to the file for the Linux server, to pass the requests to this client and forward them to the VM.

Then I planned to connect the tap0 172.16.17.2 interface with the tap_ovpn interface of vm 172.16.17.3 to forward the packets to the Windows guest.

Can I directly use the tap0 openvpn interface for qemu?
How can I prevent qemu from automatically assigning the network interfaces to the br_inet bridge?

You cannot connect to any Google service through Wireguard VPN hosted on Google Cloud Platform

This question was marked off topic in Superuser, so I guess this is the most appropriate community for my problem.

Since I set up Wireguard on my Google VPS, every HTTPS client connection to any Google site (search engine, YouTube, etc.) times out in TLS. There is no problem with pinging, bending http://google.com or HTTPS on other sites. What can be the cause of this problem and how can I solve it?

SSTP VPN does not connect, Windows Server 2019 / Windows 10 Home

I have a machine with Windows Server 2019 running on it, where I have routing and remote access (RRAS) installed, as well as IIS (which I am currently not using). I am using self-signed certificates issued by an independent root CA that is also installed on the server. In addition to having the AC installed in Personal Y Trusted Root Certification Authorities I have the certificate requested and issued to the client, as well as the certificate issued to the server domain under Personal. On the client (Windows 10 Home), I have the root CA certificate installed under Trusted Root Certification Authorities and the client certificate installed under Personal. I do not have a way for clients to verify the revocation status of certificates, so I have the function disabled through an edition of the Registry on the client's machine.

When the client tries to connect, it displays the following error message:

A connection attempt failed because the connected party did not respond correctly after a period of time, or the established connection failed because the connected host could not respond.

I think the reason for the failure is on the server side because an error occurs (found in the Event Viewer) when I configure the SSL certificate link to the certificate issued for the server.

Configuring the SSL certificate link in the server properties in RRAS (Image)

Error shown in Event Viewer (Image)

As the image shows, the error message on the server is:

The secure socket tunnel protocol could not be configured to accept incoming connections. The detailed error message is provided below. Correct the problem and restart the SSTP service.

Access denied.

Why does this error occur? I have logged in as the administrator account built into the server, so I should not have any problem with my user privileges, but I cannot understand why it says "Access denied."

By the way, I followed this guide to configure the SSTP VPN since I am new to Windows Server and VPN.

Strange problems with DNS, traceroute and VPN on the router

wget does not work on my router since the router's DNS queries return IPV6 as "Address 1" and IPV4 as "Address 2". wget (in busybox on the router) is not compatible with IPV6. Take my word that I can't use the IP of my API endpoint, instead of worrying about DNS.

The result format of the DNS query seems to have changed in February 3rd. No, the relevant website did not suddenly activate IPV6 on this date: they have been compatible with IPV6 since long before 2015. My ISP also implemented IPV6 in the middle of last year, but the subnet I am on is IPV4 and my public IP is also IPV4, so I don't think the provider has implemented IPV6 upstream, "bridging" IPV4 in the last mile, to have enough compatibility. I think maybe IPV4 all the way? Anyway, it is the DNS format itself that seems to have changed.

This is true in my main provider 8.8.8.8, as well as in other nameservers that I tried 1.1.1.1 and others.

Is this evidence that my ISP is hijacking DNS queries? Evidence against this hypothesis is that I get unique results from each DNS server. If the ISP was redirecting DNS queries to its own servers, the results would be the same regardless of which NS it was consulting. However, the results appear to be somewhat unique for each server consulted (nslookup google.com 1.1.1.1 is returning very different results from nslookup google.com 8.8.4.4, which would not be the case if the ISP was hijacking all queries)

To investigate more, I ran tracking routes. Interestingly, although I am using a VPN, Tracking routes for Google IP or any other do not go through VPN, but instead go through ISP addresses.

Another oddity is that My IP address is at 10,216.. subnet but the jump to 10.216.0.1 is not seen in the route plot.

While exclusively, EXCLUSIVELY for DNS servers that I have configured in the router configuration and confirmed in /etc/resolv.conf on the router, running traceroute makes them go through the VPN endpoints. (Yes, I know that VPN packets must also pass through the ISP gateways, but traceroute will only inform VPN endpoints when it sees that VPN works)

In addition, it is from this date: February 3, the same date my API stopped working, my VPN has been ultra stable. It used to fall every 2 hours and reconnect in seconds. Record the ups and downs of the VPN to check usage later. And since February 3, the VPN has not fallen EVEN ONCE. (And yes, the registration script is still working; I verified it by manually activating / deactivating VPN on the router).

I don't understand what these strange patterns have to do with each other.
to. DNS that returns the AAAA record as "Address 1" instead of further down the list. This is happening since February 3.
yes. VPN is ultrastable, also from February 3.
C. traceroute going through ISP sites even if VPN is enabled.
re. traceroute going through VPN ONLY for DNS IPs that have been entered in Settings.

And that is the question, What do these patterns mean?

How to configure the Unifi USG site-to-site VPN to the OpenVPN server

I am trying to configure our USG Unifi with a site-to-site VPN on a private OpenVPN server with several computers behind (which currently works with individual OpenVPN clients). The USG documentation to do this is a bit vague and I am looking for clarifications for these four fields:

• Remote subnets: Click Add Subnet to add an address for a remote network.

So, the remote internal subnet? If server1 is in 172.31.1.2, server 2 is in 172.31.2.3 and server3 is in 172.31.4.5, could you enter 172.31.0.0/16?

• Remote host: Enter the host name of the remote router.

Why a hostname when the next field has the IP address? Is it just the reverse search of the IP address in the following field?

• Remote address: Enter the Internet IP address and the port number of the remote router.

The Internet IP address and the OpenVPN server port of the .ovpn file?

• Local address: Enter the Internet IP address and the UniFi Security Gateway port number.

The IP address of the USG internal network or our static external Internet IP address? And what port to specify here?

man in the middle: if I am using a VPN with multiple connections allowed, can each user / device see the traffic of the other user?

If I am using one, a VPN service, but can connect up to 8 devices, can all devices / users see the traffic of other users / devices?

Or is each VPN connection creating its own tunnel, so it basically says that only 8 tunnels can be made / created at a time?
Also, once connected to my VPN, it is possible that someone give me authentication, using my VPN too, if someone is playing with a Wifi network? I mean, in theory, if you can think of something that can be done, but I wonder if this is a problem that happens often.

What I ask is that I am living in a house with several people, sometimes I realize that they have fun upstairs, when trying to configure several access points with the same name of Wifi, I worry if they can kidnap sessions even if I am on a VPN connection (as I once noticed a message on a service that I never wrote, but when I review the session logs, the only open sessions are the ones I know). I know I had I did not write this message, therefore, I am interested in how it would be done if I was on my VPN. Although I realize that they disconnect the wifi, sometimes they make me reconnect to my VPN, etc.
For my part, I set up my VPN to disconnect from the Internet, once my VPN connection goes down, but I wonder if reconnecting immediately could cause another security issue (assuming VPNs have handshakes as a point of wifi access).
Would it be safe to say that I should invest in my own wireless router and set up a firewall? Originally, I wanted to use my Linux box with two wireless cards, set up a new wireless network with a firewall and then create a new Hotspot, protecting my devices a little more.

  1. Question Cheap VPS for private VPN

    Hi everyone!
    I am looking for a VPS with an IP Cogent to create my own private VPN. I discovered that Cogent ips like block 38.x.x.x are not blocked by most services that do not work from a vpn, so I would like a vps provider that uses that type of ips.
    Thanks in advance
