What is the difference between routed-based vs policy-based VPN?
A route-based VPN creates a virtual IPsec network interface that applies encryption or decryption as needed to any traffic that interface carries. Route-based VPNs are also known as interface-based VPNs. A policy-based VPN is implemented through a special IPsec firewall policy that applies encryption to traffic accepted by the policy.
How do you select between IPsec vs SSL VPNs?
IPsec VPN operates at the network layer, so its configuration is generally more complex, requiring a greater understanding of potentially complex networking configurations, encryption, and authentication. However, IPsec VPN is the best solution for gateway-to-gateway VPNs connecting two or more private networks together over the Internet
SSL VPN configurations are usually simpler than IPsec VPN configurations. All the complex networking is handled by the network infrastructure and the VPN configuration can focus on high-level communication requirements, access control, security profiles, and endpoint control.
