Please check the original softether-autoinstall by icoexist here.

This is icoexist SoftEther autoinstaller that I modified to fulfill my own need, in case you need the original autoinstaller please visit the original dev. This script will hopefully make your life a little easier. I have not made any modifications to the SoftEther VPN Project code at all, this script simply downloads the latest build and compiles it for use on your supported system.

To get started, all you have to do is copy/paste the provided code for your OS. The script will handle everything else for you. Refer to the Quick Start Guide if you need to get set up quickly. Also refer to the Commands List should you need them.

• Supported Operating Systems
• Open Ports for SoftEther VPN
• Using Local Bridge on SoftEther VPN

• Uninstall Script

• Update Script

• Quick Start Guide
• Other Options
• Commands List

• Information

wget -O se-install https://raw.githubusercontent.com/AmurS/softether-autoinstall/master/ubuntu/se-install-ubuntu.bash && chmod +x se-install && ./se-install

curl -o se-install https://raw.githubusercontent.com/AmurS/softether-autoinstall/master/centos/x64/se-install-centos.bash && chmod 770 se-install && ./se-install

In terminal, execute the following:

ufw allow 443,1194,5555/tcp && ufw allow 500,1701,4500/udp

Please make sure you allow the port you use for SSH, otherwise you risk blocking inbound SSH connections. You can use ufw allow ssh or if you have set a custom port, use ufw enable x/tcp where x = port. For instance, if I use port 2222 for SSH, I'll use ufw allow 2222/tcp.

Now enable UFW with

ufw enable

The Local Bridge Setting on SoftEther VPN allows you to run your own DHCP server on the VPN. This has much better performance than the built-in SecureNAT function. For instance, you can expect your Internet throughput speeds to increase by 100+ mbps (if your connection can handle it). It is important that you manually configure SoftEther VPN to use the new local bridge after setting this up. It will be outlined below.

By default, the IP addresses handed out by dnsmasq will be 192.168.7.20 - 192.168.7.100. The default gateway is 192.168.7.1.

If in some case you need to use a local or custom DNS for your VPN. It could be configured manually by adding this line in dnsmasq.conf

dhcp-option=6,192.168.7.3,1.1.1.1,1.0.0.1

192.168.7.3 (local DNS) 1.1.1.1 (Cloudflare DNS) 1.0.0.1 (Cloudflare DNS)

There's two methods of doing this. If you've already set up the SoftEther VPN Server, use the script below.

wget -O se-install https://raw.githubusercontent.com/AmurS/softether-autoinstall/master/ubuntu/se-install-ubuntu.bash && chmod +x se-install && ./se-install

If you are just now installing SoftEther VPN Server, then select option 1 when asked "Are you going to use the bridge option on the VPN server?".

Disable SecureNAT

• Open the SoftEther VPN Server Management Utility
• Connect to your VPN server
• Select the VPN hub (or whatever hub you use on the VPN server) and click “Manage Virtual Hub”
• Click “Virtual NAT And Virtual DHCP Server (SecureNAT)”
• Click Disable, then exit to main configuration screen

Create Local Bridge

• Click “Local Bridge Setting”
• Under “New Local Bridge Definition” select the VPN hub (or whatever hub you use on the VPN server)
• Select the “Bridge with New Tap Device”
• Name the device soft and click “Create Local Bridge”
• Verify that the new device was create by running ifconfig tap_soft in a SSH terminal session. You should see something like this:

!Output example

We need to create a file in /etc/sysctl.d/ to enable ipv4 forwarding. Use the following command to create this file:

nano /etc/sysctl.d/ipv4_forwarding.conf

and insert the following into the file:

net.ipv4.ip_forward = 1

Again, save and close the file by hitting Ctrl + X then [ENTER].

Now we must enable this new option by issuing the following command: sysctl --system

Now we need to add a POSTROUTING rule to iptables to correctly route traffic and enable NAT. Please replace [YOUR VPS IP ADDRESS] with the public IP address of your server.

iptables -t nat -A POSTROUTING -s 192.168.7.0/24 -j SNAT --to-source [YOUR VPS IP ADDRESS]

This rule will exist until the next system reboot, so to keep it persistent we will install iptables-persistent

apt install iptables-persistent

If everything above was done correctly, all we need to do now is to restart the DHCP server and the running SoftEther VPN server.

/etc/init.d/dnsmasq restart && /etc/init.d/vpnserver restart

Check out the forum post here for a more in-depth explanation. If you can't seem to get your server to work at all, try running the install script again so you get a fresh start.

As of now, this bash script will only work with Ubuntu due to the use of update-rc.d.

wget -O se-uninstall https://raw.githubusercontent.com/AmurS/softether-autoinstall/master/ubuntu/se-uninstall.bash && chmod 770 se-uninstall && ./se-uninstall

wget -O se-update https://raw.githubusercontent.com/AmurS/softether-autoinstall/master/ubuntu/se-update.bash && chmod +x se-update && ./se-update

To execute SoftEther's cmd utility, use sudo /usr/local/vpnserver/vpncmd <-- This applies if you used my scripts. If you've installed SE yourself, find the vpnserver directory.

With vpncmd you are able to change every option in regard to SoftEther. It has the same exact purpose for the GUI version you can obtain on MacOS and Windows. I encourage people to use vpncmd because it can be easier than the GUI, plus there's no need to download anything since you can configure the entire server from an SSH session.

It is important that you set a server password. This should be the first thing you do after launching the vpncmd utility. To set a password, type serverpasswordset into your terminal after you've launched the vpncmd utility. For verification, you have to type the password twice.

This section will provide you with a list of things to get you started with your VPN server. I'll have more commands listed below this section.

1. Start the vpncmd utility with sudo /usr/local/vpncmd

2. Set a server password with ServerPasswordSet

3. Select the DEFAULT hub with hub default

4. Create a new user with UserCreate | You can either use UserCreate or UserCreate [username]

5. Set a password for the new user with UserPasswordSet | You can either use UserPasswordSet or UserPasswordSet [username]

6. Enable SecureNAT for the DEFAULT hub with SecurenatEnable

   Optional: You can enable L2TP/IPsec with IpsecEnable. It is recommended that if you use this option, you only enable L2TP/IPsec. Do not enable RAW L2TP w/o encrpytion. You will be asked to set a pre-shared key for the IPsec server, you can use anything. I've used vpn as a pre-shared key for ages. Remember that this is NOT a password for the server or a user, so it's safe to use that. You'll also be asked for the default hub in the event that a user does not specify the hub to connect to in their username, you'll set this to default if you haven't changed any hub names. If you're more advanced user and have multiple hubs, you can specify what hub a user connects to by putting it in their username on the client. For instance icoexist@public or icoexist@hub2.

If everything was done properly, you're ready to use your new VPN server! To add new users, just launch the vpncmd utility and repeat steps 3 - 5.

You can change the ports that SoftEther VPN server will use to listen for incoming connections. If you're using the vpncmd utility, you can list the current ports with listenerlist.

ListenerCreate - Creates a new listener on a specified port
ListenerDelete - Deletes a listener on a specfied port
ListenerEnable - Enables a listener on a specified port
ListenerDisable - Disables a listener on a specified port

SoftEther VPN server allows you to manage users and their policies. Below are some popular commands and descriptions on what they do. Remember that you first have to select a hub before you can manage users, as each hub has its own users.

UserList - Displays a list of users
UserGet [username] - Displays information on a specified user
UserCreate [username] - Creates a user
UserPasswordSet [username] - Sets a password for specified user
UserDelete - Deletes a specified user
UserPolicySet - Sets a policy for a specified user | It is recommended that you enable "Privacy Filter Mode" on all newly created users on the same hub, unless you WANT them to see each other. To do this, type UserPolicySet then when it asks for what policy, type PrivacyFilter. It will ask for the new value, to enable it enter 1, to disable it enter 0.
UserPolicyRemove - Removes a policy from a specified user

SoftEther VPN server also allows you to manage virtual hubs and their policies. Below are some popular commands and descriptions on what they do. Remember that you first have to select a hub before you can manage it.
