1720 and VPN [7:48183]

Does anyone know if the 1720 Cisco router supports IP SEC VPN without buying the VPN module? I read a couple of articles about VPN and modules and am a little confused. Thanks for the help Len Message Posted at: http://www.groupstudy.com/form/read.php?f=7i=48183t=48183

VPN modules [7:48187]

What is the VPN module used for on the Cisco 1720 if the router has the capability in the IOS? I want to do IP SEC VPN and I was told that it is supported without the VPN module. Just wondering the difference between the two. With and w/o the module. Thanks in Advance Len Message Posted
