Hi all, 

   ASAIK, some vendors like Netscreen, or Shasta from Nortel, or I 
thinks also Cosine (but I am not sure about it) support NAT in such a 
way that can be used for MPLS VPNs, for providing Internet connectivity 
for a customer corporate VPN. 
   Cisco is also due to release that feature for MPLS VPNs. 
   Now my question is (mainly targeted to people working in service 
providers but in general to all): Is currently the Internet 
connectivity for the VPNs being integrated in the VPN service using 
this kind of devices/features or is actually using mostly the 
traditional model based on two physical/logical links in the main site 
of the customer, one for the VPN and one for Internet. 
   The point is, what is being preferred by service providers and why? 
I think integrating the Internet and VPN service in the same interface 
(physical and logical) as any solution that integrates several services 
toghether reduces the churn (i.e. the rate of losing customers going to 
other service providers), but in practice, how many providers build the 
service this way?
   Thanks in advance for your oppinions.
   Javier.
