you probably want to use natd to do this rather than ipfw fwd.. ipfw fwd does not change the packet, but, rather, just delivers the unaltered packet somewhere. (This can be useful, but not for what you want to do). Now, if the web server was running FreeBSD you might be able to do it, but otherwise you need to actually change the packets so that they reflect the new target. Natd can actually do this I believe. (it also uses IPFW so you haven't wasted the effort you have done so far.) julian On Wed, 4 Aug 1999, Kent Ho wrote: > Hi, > > I have recently moved one of our webserver from my network to an ISP > data center assigned with a new IP address. > > The problem is that lot of machines out there still trying to find the > webserver at the old IP.
