IP masquerading cannot provide full internet connections to the hosts which hide behind it. The reason for this is that any connection can be established outwards, that is a hidden host can connect to any service which is “advertised” on the internet, but no connection NAT aka Network Address Translation is a method for routing IPs.

When --nat-outgoing option is used, Calico performs NAT for the outgoing traffic by adding a rule in the nat table that uses the MASQUERADE target: Masquerading is the Linux-specific form of NAT (network address translation) and can be used to connect a small LAN with the Internet. LAN hosts use IP addresses from the private range (see Book “Reference”, Chapter 13 “Basic Networking”, Section 13.1.2 “Netmasks and Routing”) and on the Internet official IP addresses are used.
