A communication network includes a plurality of nodes, selectively including a
client, a remote gateway Internet service provider, the Internet, a local enterprise
gateway, and an enterprise internal network. A local coincident endpoint is established
at a first node for an outer connection with a remote node and an inner connection
with a different remote node. The nodes participate in negotiations on the outer
connection to set up the inner connection as a secure connection. Thereafter, responsive
to communications on the inner connection, the first node establishes links to
the outer connection selectively to receive or send communications double nested
on the outer connection.
