Client VPN doesn't work on my Linux

Post by drazde » Mon Mar 09, 2020 9:06 pm

I try to configure Client VPN on Linux.

I run `vpnclient`, create an account and Do `AccountConnect`

Code: Select all

VPN Client>AccountList
AccountList command - Get List of VPN Connection Settings
Item                        |Value
VPN Connection Setting Name |VPN_XXX
Status                      |Connecting
VPN Server Hostname         |XXX.XX.XX.XXX:YYYYY (Direct TCP/IP Connection)
Virtual Hub                 |VPN Test
Virtual Network Adapter Name|VPN
The command completed successfully.
Seems to be all ok but doesn't work, I can't reach any pc on my network.

The status is Connecting and not Connected why?
The VPN Tools Check work fine...

Code: Select all

VPN Tools>Check
Check command - Check whether SoftEther VPN Operation is Possible
SoftEther VPN Operation Environment Check Tool

Copyright (c) SoftEther VPN Project.
All Rights Reserved.

If this operation environment check tool is run on a system and that system passes, it is
most likely that SoftEther VPN software can operate on that system. This check may take a
while. Please wait...

Checking 'Kernel System'...
Checking 'Memory Operation System'...
Checking 'ANSI / Unicode string processing system'...
Checking 'File system'...
Checking 'Thread processing system'...
Checking 'Network system'...

All checks passed. It is most likely that SoftEther VPN Server / Bridge can operate normally on this system.

The command completed successfully.
I use also windows and with the same configurations the vpn works

Sorry but I'm a newbie
I forgot to set the password with `AccountPasswordSet`

Now I have this situation, seems to be ok, but i cant't ping any pc.
Is it a routing problem?

After a while, i can reach every pc, it is a routing/dns problem...
How can I update immediately?

You could use a script to check if the remote gateway can be pinged. If so, add your routes. Please note you'll have to change the <code>gateway_ip</code> in the code below and add the routes that are relevant for your network.

Code: Select all


# Script to determine if VPN is up


# Change below to the path for your vpnclient executable
./vpnclient start

# see if the VPN is up by pinging the gateway
cmd=$(ping -c 3 ${gateway_ip} |egrep "3 packets transmitted" | awk ' { print $4 } ')

if [[ ${cmd} -ne 0 ]]

	# The host is up so add the route
	sudo route add -net NETWORK dev GATEWAY
	echo "The VPN is not up."
