We want to force the use of our web caches. Our boundary router is a 3Com NetBuilder II, which we can get to forward port 80 traffic to another IP address. However, it does not rewrite the destination IP address in the IP header. Thus the machine has to be directly connected to the router to actually get the packets. What I'm wondering, is can FreeBSD cope with this? Will it be able to process these packets, with an IP address that is not it's own, at all or is this a non-starter? I suppose if it can then a more elegant solution to our caching needs can be found. We have two caches and would ideally like to spread this forwarded traffic across them. Could a 3rd FreeBSD box be plugged directly into the router and selectively forward packets to both servers? This would enable load balancing of this enforced traffic. Thanks for any help, as it's the first time I've even attempted anything like this. I'm assuming that ipfw or ipfilter will be what I want, but I have little experience of them. Cheers.
