Enable disable vpn from browser

[carefulcomputer]

I have setup ipsec vpn on my router and my laptop and it is working fine. Now I am trying to enable/disable VPN using based on some triggers from laptop.
I checked the http call made by web browser to server when I enable/disable the VPN (using chrome dev console). Looks like when clicking the 'apply' button it sends all vpn parameters and 'start/stop' command in POST payload.

Is there a way to only enable/disable VPN using HTTP call without sending all parameters (i.e. psk, user/pass etc ?).

I am answering my own question. Yes, you can. I found only some of parameters can be sent to turn on/off VPN. Above post was about IPSec vpn, but I found that to be unstable (causing router to reboot). So I switched to openVPN. Here are parameters for turning on openVPN , rest of parameters need not be sent.

'current_page': 'Advanced_VPN_OpenVPN.asp',
'next_page': 'Advanced_VPN_OpenVPN.asp',
'modified': 0,
'action_mode':'apply',
'action_wait':15,
'VPNServer_mode':'openvpn'
'action_script' : 'restart_chpass;restart_vpnserver1';
'VPNServer_enable' : 1;
'vpn_serverx_start' :'1,';

Why not use SSH?

OpenVPN server 1 (change the number for the second instance):

service stop_vpnserver1
service start_vpnserver1

PPTPD:

service stop_pptpd
service start_pptpd

Console cmd to Start/Stop/Restart OpenVpn/PPTP VPN server

Hi all, can someone help me with console commands to start/stop/restart/status OpenVPN server and PPTP VPN server service? I am not familiar with it and service pptpd_start is not working :/ No luck with google also :/ Thank you

that's a good point. My triggering client is javascript. For ssh I would have to shell out to console. Not a big deal, but HTTP is little more convenient.
