Transport mode | Tunnel mode |
---|---|
Here end hosts do IPsec encapsulation of their own data; hence IPsec needs to implemented on each end-hosts | IPsec gateways provide service to other hosts in peer-to-peer tunnels; hence the end-hosts don’t need IPsec. |
Lower overhead than tunnel mode | More overhead required |
