You > may also need to muck about with ``set redial''. In my situation, I'm using a PPPoE link for my LAN, which contains web and mail servers. I need the link up 24/7, so background and auto are inappropriate. (Background will try once and either succeed or fail. In the failure case, that means that I have to restart ppp by hand. Auto will drop the connection once internal traffic ceases, which will close off access to my public servers when I'm not using my system - I do get a considerable amount of web and mail traffic to my sites while I'm sleeping.) Hence, I need to use ppp_mode=dedicated (or ddial) in order to keep the link up 24/7. > The thing that concerns me is why you say it's sometimes necessary > to use natd instead of ppp's -nat switch (or ``nat enable yes''). > Under what circumstances is this necessary ? To do port forwarding, for one. PPP's nat support is "nat enable yes|no", which may be great for a LAN, but not a gateway machine with servers behind it that need port redirection. -- Matt Emmerton To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
