General Discussion / As for plug-ins in the forum

« on: September 24, 2019, 01:04:04 pm »

Hey,

Because there's a squid and proxy part. Is it good to have one of your own specific plug-ins?พนันบอลออนไลน์ฟรีufabet2019

There may be a post at the top with an overview of the entire power plug including their compilers. Will this make it possible to place a bug report and request features directly with the plug-in developer more easily?


Reverence,

Russian - Русский / DynDNS для IPv6 не работает

« on: March 28, 2019, 08:02:02 am »

Привет,

У меня проблемы с регистрацией IPv6-адреса WAN-интерфейса брандмауэра у моего оператора DynDNS. Я получил следующие результаты:
สล็อตฝากไม่มีขั้นต่ำ
Регистрация адреса IPv4 с помощью встроенного клиента DynDNS (Custom) работает нормально
Регистрация адреса IPv6 с помощью встроенного клиента DynDNS (Custom v6) завершается неудачно
Запуск URL регистрации IPv6 через командную строку с помощью curl работает нормально

Захват пакета показывает, что клиент DynDNS не связывается с сервером, но в файле журнала отображается следующее сообщение об ошибке, даже если интерфейсу WAN назначен публичный IPv6-адрес:

opnsense: /services_dyndns_edit.php: Динамический DNS (<имя хоста>) Произошла ошибка при попытке определить публичный IP для интерфейса - wan (ix0). Вероятно, интерфейс не является интерфейсом WAN.

General Discussion / Enable or disable Windows Firewall from Command Prompt.

« on: March 24, 2019, 06:04:13 am »

Manage Windows Firewall from a command prompt
First, see if Windows Firewall is enabled on the server or computer. Type this command at a command prompt:

netsh advfirewall show allprofiles
Make sure you open an administrator command prompt (click Start, type CMD, then right click on Command Prompt and choose Run as Administrator). You should get something similar to what is shown below. :

By default, you should see three separate listings here: Setting up a domain profile, personal profile Public profile settings and settings These three types match three states. You can place each network connection on your computer. If you connect to your home network and select Home Network, the system will use your personal profile settings.

State means if the firewall is on or off, the firewall policy tells you how incoming and outgoing policies are applied to each profile.

To disable the firewall for a specific profile, you will use the following command:

So if you want to disable all firewalls, you will use allprofiles instead of personal profiles If you want to reactivate it, place it on the end instead of closing it.
Open ports in the firewall using the command line.
Now what to do if you want to open a port in the firewall using the command line? too easy

Suppose you want to open port 3389 which is used for remote desktop in Windows. You will run this command:

netsh advfirewall firewall add rule name = "Open Remote Desktop" protocol = TCP dir = in localport = 3389 action = allow
This statement is quite long. But quite easy to break down You can add rules to names, select protocols (TCP or UDP), choose the direction (enter or exit), give the port number and select the action. (Allow or reject)

If you want to run this command, then go to see the apps that are allowed in the Windows Firewall. You will see that the Remote Desktop list has been checked:



If you want to open various ports, use a simple dash. For example, here I open ports 600 to 7000 for UDP outbound traffic:

netsh advfirewall firewall add rule name = "UDP ports" protocol = UDP dir = out localport = 6000-7000 action = allow
There are many advanced commands that you can use to manage all aspects of Windows Firewall. So make sure to use characters. /? At the end of any order to see all options and examples

General Discussion / OpnSense Firewall OpenVPN

« on: February 28, 2019, 11:26:38 am »

It requires a few steps, but this will get you up and running with an OpenVPN client on your OpnSense and probably pfSense) router.

Steps:

Download VyprVPN Certificate150
Identify the server you want to use101

System --> Trust --> Authorities --> Import Golden Frog CA Cert (copy & paste it in from a text editor), name it VyprVPN

VPN --> OpenVPN --> Clients --> Add (with following settings)
Server Mode: Peer to Peer (SSL/TLS)
Protocol: UDP
Device Mode: tun
Interface: WAN
Local port: (blank/empty)
Server host or address: us6.vpn. goldenfrog.com (use your server of choice here)
Server port: 443
Proxy host or address: (blank/empty)
Proxy port: (blank/empty)
Proxy authentication extra options: none
Server host name resolution: (unchecked)
Description: VyprVPN
User name/pass: Username: (your email address)
Password: (your password)

Cryptographic Settings

TLS Authentication: (unchecked)
Peer Certificate Authority: VyprVPN (see above, Import CA)
Client Certificate: None (Username and Password Required)
Encryption algorithm: AES-266-CBC (256 bit key, 128 bit block)
Auth Digest Algorithm: SHA256 (256-bit)
Hardware Crypt: (use it if you have it, e.g. Intel RDRAND engine - RAND)

Tunnel Settings (all blank or unchecked except)

Compression: Enable with Adaptive Compression

Advanced (add these to advanced):
resolv-retry infinite
keepalive 10 60
persist-key
persist-tun
persist-remote-ip
verify-x509-name us6.vyprvpn.com name
verb 3
tls-cipher TLS-DHE-RSA-WITH-AES-256-CBC-SHA
redirect-gateway autolocal

(Check the logs to validate the name above [us6.vyprvpn.com] to match the certificate and server you are connecting to)

Verbosity Level: 3 (Recommended)
Start your client and look at the logs, you should get a successful startup, but you are not done yet.

openvpn[49494]: Initialization Sequence Completed

Firewall --> NAT --> Outbound --> Set to Hybrid
Add a manual rule
Interface: OpenVPN, leave the rest as defaults and save

Now go the web and see what it says, your home city or your VPN location.
Check What's My IP

*Try a trace route and you should go through the VPN IP address. Look at the VPN logs to see the VPN IP and static routes being created.

Good luck!
