-----BEGIN PGP SIGNED MESSAGE----- For what it is worth, the wavesec network has a reverse map. Put: option oe-key code 159 = string; option oe-gateway code 160 = ip-address; send oe-key = "16896 4 1 <some-base64>"; request subnet-mask, broadcast-address, time-offset, routers, domain-name, domain-name-servers, host-name, oe-gateway; require subnet-mask, routers, domain-name-servers, oe-gateway; in your dhclient.conf, and you'll get an IP on the other network, which has reverse. see www.wavesec.org. I don't know yet how to do this for OS/X, or the LookOut OS. We offered to help the hosts do the reverse map for the rest, but it wasn't possible to get the right people there on Saturday/Sunday. ] At IETF57 in Wien, Austria | firewalls [ ] Michael Richardson, Sandelman Software Works, Ottawa, ON |net architect[ ] mcr@sandelman.ottawa.on.ca http://www.sandelman.ottawa.on.ca/ |device driver[ ] printk("Just another Debian GNU/Linux using, kernel hacking, security guy");[ -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.0.7 (GNU/Linux) Comment: Finger me for keys iQCVAwUBPxaMX4qHRg3pndX9AQGYxQP+NyjTQql46P1RjKbw2c7jivx/mHv45tJI JhKFeQGACUaxEAgoKYJU4utAJmEtnts8UiuyJg4J7xuEULEdM/raaYaCVmhLpFmV yF/XMk1al5KXWsF+xYrw3x/bty6GoYp0XexDlhkdHJOQb7ORILFSsciyU0TWRX0I jhQvyWw7lhQ= =GH5u -----END PGP SIGNATURE-----
