I was going to give him the standard response regarding policy routing and "fwd" rules in FreeBSD's IPFW, but then remembered that the RADIX_MPATH option is supposed to be implemented in FreeBSD 8.1. Is there documentation on the use of this kernel option? How can multiple gateways be specified in rc.conf? What else does one need to know simply to answer requests (say, for a Web server) via the gateway through which they arrived? To do load balancing? Is there a HOWTO or man page? (I couldn't find one, but may have missed it.) --Brett Glass
