I've done a bit of research on pppd in the past and seemed to be recalling that it is capable of on-demand connection to the ISP - i.e., that it can await requests for the 'net and then dial the connection, whether these requests originate from the localhost or somewhere on a LAN. I used diald at the recommendation of someone else, who seemed to think it would be what I'd need for my small home network. He proposed it as a way that would allow the machine that will act as the gateway to watch for internet connection requests from the network and dial the connection. Perhaps he was a bit outdated, and should have suggested that pppd can now serve these sorts of functions?

There is one other, and may be as many as 2 more machines on the LAN that will need to connect to the 'net via this computer. Getting something like diald working - or just pppd, if it will do the job - is a preliminary step, mainly calculated to buy me time as I try to digest the much more difficult (and more fundamental) problem of ipchains. I've got the howto for it, but it's got this newbie's brains quite taxed. I'll doubtless be posting some questions on that related topic in the not-too-distant future. I do want the user to be able to break the connection to the 'net as you suggest, and not necessarily stop diald. I wasn't sure there was a difference, but your post makes it clear that there is.

Probably no big worries there. I think I just got some rather dated advice on how to set up demand dialing.
