Cisco VPN connection fails

hello,

I am trying to configure a Cisco 857 router to accept VPN connections from home.

however i think the reason this is not working due to a missing command.. but as i don't know cisco too well so i could be wrong.

this is where i think the missing command is missing from:

interface Virtual-Template1
 ip unnumbered FastEthernet0
 no ip redirects
 no ip unreachables
 no ip proxy-arp
 ip nat inside
 ip virtual-reassembly
 peer default ip address pool defaultpool
 ppp mtu adaptive
 ppp authentication ms-chap ms-chap-v2
 ppp eap local

missing: 'ppp encrypt mppe auto' (this is not available in the ISO)

when i try and connect  to the router with the VPN i get the following error:

error 742: The remote computer does not support the required data encryption type

is the 'ppp encrypt mppe auto' required to connect with VPN?
is there a work around?
would the missing command give the error above?

Regards,

check your settings on the client, under properties, then under security check advanced, then click settings, under there make sure the data encryption is set to optional, then further down check allow these protocols, select ms-chap and ms-chap v2.
then try and connect.

i have tried this, and then it gives me an error when registering your computer on the network

Error 720: a connection to the remote computer could not be established you might nee to change the network settings for this connection.
