Barney, you wrote: > At first glance, you can't do what you want with only a /29.

Yes, which is why I said I could only have two of the required three subnets, using a standard, "correct" design. But thanks for noting that; I expect my list of current IP assignments seemed to imply my ignorance of that "requirement". But it seems to work, regardless; just awkwardly. I'm thinking it would be nice if the network software could do for me what I am now doing manually or with scripts. But, there are likely reasons for it I don't see yet. > can get an Ethernet to work as a point-to-point link because the > driver needs to arp.

But I'll do some net searching later and try to learn some details of that point-to-point stuff. > One thing you might try is to replace the DSL router with a mere > DSL modem, or, if possible, put the DSL router into bridge mode. > That way, the firewall can use the external address that was > assigned to the DSL router (which is in some other netblock than > your /29) as its external address, and then a hub or switch on > the internal side will connect all your other boxes. I run my > DSL /29 this way. Good suggestion, but I doubt my ISP would go for it. I had to reconfigure it from bridge to router when I switched to them. (Before that I only used one computer and DHCP). You probably already know that the DSL box has many more features when run in routing mode, though its debatable if they are worth much. > This is not a matter of documentation - what you're asking route > to do cannot be done. I think it IS a matter of documentation that I have to resort to experimentation to learn what "route" and "ifconfig" will do and what they do and even the fine points of their command syntax. Also, I could say that "route" (and other software) IS doing what I want; it's just awkward to get it to do it and hard to learn how. I hope that didn't read too snippy for you. I do appreciate your having sent your comments and FreeBSD contributors for making it available at all, and I hope to help make it better (and already have in a few PRs and doc patches).
