If you want to use natd, you should use it's redirect_port feature instead of mixing the networks. This way you get the filtering feature of natd protecting your mail and web server. The downturn is that you loose flexibility on your web server -- if you add services you'll have to set up redirect rules for it. I don't know how fancy your router is, if it can be taught to natd certain packets or not (I think ipfw can do it, not sure). > I'have tried assigning 2 ip address at the same interface ,and using > this machine as a gateway on the same phisical net. You have to use an alias (with the netmask of that network, not 0xffffffff) on the interface to get the second IP programmed in.
