I have a BEFW11S4 running firmware 1.50.14. Under the security tab, it allows me to turn on VPN flavors, IPsec, PPPoe, and PPTP. But I can not figure out how to configure them in the router or anywhere else for that matter. Any suggestions or directions. Is VPN even possible with this unit. I know it was not marketed as on the box as supporting VPN, and the VPN options only came up after a firmware upgrade. Many thanks for your consideration.
