Connect Chromebook to UTM using SSL VPN

Question

Hi, 
 We have the VPN working on Windows but can't seem to connect Chromebooks. 
 The existing threads point to blog entries that no longer exist. 
 Is this possible? In a way that our users can follow? 
 Thanks 
 Steve

Hi, 
 the website seems to be offline. 
 I ran into the same problem - using the sophos ssl vpn with our chromebooks - here is my solution: 
 
 set up your ssl vpn 
 log into your UTM with the admin account
 
 goto Remote Access 
 goto Certificate Management 
 download user certificate as PKCS#12

log into your UTM user portal with the user account, who needs the ssl connection 
 
 go to remote access 
 download the OpenVPN configuration file (.ovpn)

get my onc template 
 edit the template according to your IT configuration
 
 "GUID": "{get one at www.uuidgenerator.net}", 
 "Name": "name of connection in ChromeOS", 
 "Host": "IP.address.or.domain.name.of.my.utm", 
 "Port": 443, 
 copy & paste the ca-certificate and the user certificate from the .ovpn file into the .onc file (-----BEGIN CERTIFICATE----- .... -----END CERTIFICATE-----) 
 remove the wordwraps between -----BEGIN CERTIFICATE----- and -----END CERTIFICATE----- 
 save

log on to your chromebook with the user account, who needs the ssl connection
 
 open chrome://settings 
 search for certificate 
 open the certificate manager 
 import the user certificate hardware backed 
 open chrome://net-internals#chromeos 
 import the edited .onc file by using "Import ONC file" - there will be no confirmation!

open the VPN connection in settings and start it 
 enter the username and password 
 
 Steps 5.a through 5.g should be scriptable using powershell. 
 Cheers,
