then click on the wifi icon on the top right of your screen. make sure you are connected to the internet. move down to VPN connections/ Configure VPN
input all of your information and credentials.
go back to the wifi icon/VPN Connections/ (choose your newly added connection)

the type of vpn, is it pptpor l2tp or ipsec? you can call E-lins tech
