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 ..
