Are you trying to give the older boxes IPv6 connectivity or IPv4 connectivity to the Internet? If IPv6, why not just give the older boxes IPv6 addresses? Seems to me it would be a lot easier than messing with tunneling. They don't even need globally routeable IPv4 addresses. Set up rtadvd on your router, allow them to use their automatic IPv6 addresses (or set the addresses manually, doesn't matter), and that should be it. It shouldn't be that hard, since ease of setup is one of the things IPv6 is designed for. On FreeBSD, ipv6_enable=3D"YES" is probably all you need to do. --=20 Kenyon Ralph --p2kqVDKq5asng8Dg Content-Type: application/pgp-signature; name="signature.asc" Content-Description: Digital signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) iEYEARECAAYFAkr4nBYACgkQmFtUtJKnbnWs8wCfetbRevDlhx0a2cOsJdwLpgka 93QAoKbNd/IB7xEyu2/izzcp7bK3ti+Z =F0RV -----END PGP SIGNATURE----- --p2kqVDKq5asng8Dg--
