I have a solution for exactlythis problem You need the patch I submitted for ipfw fwd of incoming packets about 3 weeks ago. it allows load sharing to an arbitrary number of webservers transparently I sent it to "net" and it had a subject of RFC: (something) the mail includes how to set it up.. it uses about 1% of cpu redirecting a 10Mb ethernet to 2 servers. (sorry to be vague but look it up in the archives with julian AND RFC AND ipfw in the net list.. On Tue, 11 Dec 2001, Tom Peck wrote: > Hello > > We have ONE static IP with our ISP via a Cable Modem.
