Hi..I need to connect 10 sites with no web portal,public users...which is better between lease line or VPN ..is there a need of firewall?...Does VPN also covers the L4-L7 securities ??..should I go for lease line or VPN ??
When I go for VPN, still there is a need of Firewalls to provide the L4-L7 securities if Web servers are there ...??
Please suggest me ..

In my opionion - there is no right ro wrong answer, you need to consider:-
1) Cost
2) Number of devices to manage
3) Cost
VPN's are cheap - becuase internet circuits are cheap, but you have contention ratios, reliability issues and banwdith contrants.
Leased lines are not cheap - but you do get 100% of the bandwdith you buy.
With a leased line - you do not need a firewall, with the VPN you do.
The VPN can cover L4-L7 security.
If you go for a VPN yes you should use a firewall.

Sanjev,
You either need a firewall or router both with a crypto image to establish a VPN. As the router can also have a firewall software installed - you secure the traffic.
As explained - a lease line is a point to point circuit. Read the below for more information:-
