I'm a novice user, how can I tell if we are using PPTP/L2TP and IPSec?
I wonder if you know of a link, which simply explains the Stages of a VPN tunnel, phase 1 phase 2 etc? A lot of the googel searches go very deep for a novice user.

this gives you the basic knowledge on phase 1 and phase 2
Thanks

When you are using commands like
fw1(config)# isakmp policy 10 encryption des
fw1(config)# isakmp policy 10 hash sha
fw1(config)# isakmp policy 10 authentication pre-share
fw1(config)# isakmp policy 10 group 1
fw1(config)# isakmp policy 10 lifetime 86400
for phase 1 vpn to define policies
you will know that we are usin ipsec
Thanks

I use a Cisco Concentrator 3015, don't really use commands. The VPN connects to Cisco 837's for Lan-2-Lan's. On the router I see this sort of config:
crypto isakmp policy 1
encr 3des
hash md5
authentication pre-share
group 2
crypto isakmp key password address 1.2.3.4
!
!
crypto ipsec transform-set vo_t_set esp-3des esp-md5-hmac
!
crypto map vo_t_set 10 ipsec-isakmp
set peer 1.2.3.4
set transform-set vo_t_set
match address 101
