The term masquerade relates to identity concealment. Routers impersonate original request senders bound for internet, but remember internal network originating nodes. Internet resources respond to routers as if connecting with original senders, but routers modify packets forwarding to original requesters. Routers present LAN clients to external worlds under different identities - WAN IPs, concealing private addresses behind public ones. Clients appear to remote servers as routers themselves. Routers hide client original addresses. The kernel implements masquerade actions in nf_nat_masquerade.c within net/netfilter/.
