well since your router will be doing nat for you more than likely, then your linux box should have an internal ip address. So unless you forward the correct port on the router to the linux box, then no one should be able to see it. This is all assuming that you have an internal ip and your router is doing nat for you

NAME
rrenumd -- router renumbering daemon SYNOPSIS
rrenumd [-df] [-c conf_file | -s] DESCRIPTION
The rrenumd utility transmits router renumbering request packets, to renumber the routers in the site network. On KAME-based systems, router renumbering requests are received and processed by rtadvd(8). For other systems, refer to relevant documents. The program will daemonize itself on invocation. It reads configuration information from standard input if -s is specified, or from conf_file if -c conf_file is specified. The contents of configuration information are described in rrenumd.conf(5). After successful configuration, rrenumd sends router renumbering messages periodically to configured destinations. Messages contain prefixes configured to be renumbered. -d Debug mode. -f Foreground mode. Do not become daemon. -s Script mode. Configuration information is obtained from standard input. -c conf_file Specify a configuration file where configuration information is kept. EXIT STATUS
The program exits with 0 on success, and non-zero on failures. SEE ALSO
rrenumd.conf(5), rtadvd(8) STANDARDS
Matt Crawford, Router Renumbering for IPv6, RFC, 2894, August 2000. HISTORY
The rrenumd utility first appeared in KAME IPv6 protocol stack kit. BSD
