Hello! The BEFVP41 is a "Linksys by Cisco" consumer router and this Support Community is for the Cisco Small Business Product support, so we don't suppot the Linksys by Cisco products on here. You can try the Linksys by Cisco site (www.linksysbycisco.com) but also I did a quick Google search for "BEFVP41 vpn setup" and found some interesting links and information, such as this one that may be of help to you.
Best Regards,
