Hi, > Thanks for your response, I have set eth1 to the 192.168.1.1. I have a > couple of questions. > > 1. That address is obviously the same as my router? The router, being downstream of devil, should get its address via DHCP. However, it might be expecting the net upstream of it to begin with 192.168.0 > 2. Do I need to turn off DHCP on the router? I'm speculating, but I don't think that's the problem. > 3. Why must I use a crossover cable from eth1 if I choose to go directly > into my pc for testing purposes? (At least one question that I am familiar with.) Normal, 100 Mbps eth uses 2 pairs of wires (only 4 of the 8 wires on the CAT 5 are used). It was designed for one port to be on the upstream side & one on the downstream side. To connect 2 ports that were physically designed both as "downstream" or both as upstream ports (for instance, 2 ports on the backs of computers), we need a "crossover" cable, which simply has the 2 active wire pairs crossed over. Some eth receivers are electronically smart enough to figure out and compensate for the presence or absence of a crossover cable, so a crossover cable may not truly be required. The gigabit eth spec requires symmetric negotiation (like the "intelligence"), so crossover cables are not needed. > 4. Does the crossover cable go from eth1 into the WAN port of the router? Yes. From devil into the WAN port. Might possibly need a crossover cable here. > I realize some of these questions may seem quite silly, but I am quite new > to all of this. Thanks again. I normally use a simple hub in place of a router. <<<< I've daisy chained (simple home-use wireless-style) routers, but not often. Can you connect a XP or Vista machine directly into devil? Try it even if you don't have a crossover, it might work. It might work on one machine & not on another. One of my 2 laptops has a smart eth port. You won't do physical damage by misusing a crossover, the connection will merely not happen. Do you have a crossover cable? It is useful to have 1 around for sanity's sake. Hang in there. One nice thing about devil is that once it is set up, it will hopefully need nothing else. Chip |
