IF YOU DO NOT NEED TO CONNECT MORE THAN TWO COMPUTERS DO NOT USE A HUB! (did the caps get your 'tension?) the reasons are simple 1 a hub costs money and if you were into spending money you wouldn't be using freebsd you'd be dealing (and spending a fortune for the same or less effect) with a Microsoft or comperable product. And second you can't expect to get better that 60%(+-) ie: 6Mbps rather than 10Mbps throughput so you are paying for latency and collissions..Just my two cents.. -----Original Message----- From: Dave Walton <walton@nordicdms.com> To: Benedikt Stockebrand <benedikt@devnull.ruhr.de>; questions@FreeBSD.ORG <questions@FreeBSD.ORG>; isp@FreeBSD.ORG <isp@FreeBSD.ORG>; fbsdlist@federation.addy.com <fbsdlist@federation.addy.com> Date: Wednesday, February 11, 1998 9:22 PM Subject: Re: FreeBSD firewall questions On 11 Feb 98 at 22:41, Benedikt Stockebrand wrote: > Cliff Addy <fbsdlist@federation.addy.com> writes: > > > - In order to connect the outside nic of the firewall directly to the > > router, don't we need a "special" cable, the cat-5 equivalent of a > > null-modem cable? > > You can use a proper hub instead.

Standard cable: 1 ----- 1 2 ----- 2 3 ----- 3 6 ----- 6 (1,2) -> (1,2) should be a twisted pair, as should (3,6) -> (3,6). Crossover cable: 1 ----- 3 2 ----- 6 3 ----- 1 6 ----- 2 (1,2) -> (3,6) should be a twisted pair, as should (3,6) -> (1,2). If you are using 4-pair cable (and you probably are), you can hook up 4 ----- 4 5 ----- 5 7 ----- 7 8 ----- 8 for both setups.
