Equipment at either end of the link splits the 40kHz carrier off from the unmodulated voice at 8kHz. Or something like that. But it should be obvious that ethernet signalling can't run over the DSL connection; the maximum signalling distance for 10baseT is only a couple of hundred yards, and even if you were that close to your CO, haven't you ever tried running an ethernet link over phone wire? Less than Cat 4 and the ethernet carrier drops out even over a short haul. But there isn't any reason to get rid of the modem just so that you can firewall the office. Instead connect the modem to one ethernet card of a dual homed system, and connect your LAN to the other card. Turn on IPV4 forwarding and set up your firewall rules and you have a firewalled internal network. Turn on NAT on the firewall and you won't even have to renumber your internal network. But with 126 IP addresses (+network and broadcast), your friend could easily renumber the network and let IP packets get routed directly (without NAT.) === Date: Sat, 27 Jan 2001 14:25:34 -0800 From: kevin@ank.com To: "Derek J.

A 3-bit subnet for $79/mo, things are definitely getting affordable (only $10 to go...). On Sat, Jan 27, 2001 at 02:06:33PM -0800, Derek J.
