Hi all, In running up a new DSL connection today, I came across an "interesting" situation w.r.t. DHCP and point-to-point links.
The planned implementation is to have the Netgear DG632 ADSL modem do the PPPoA but pass (by DHCP) the single fixed-IP address to the Linux box on the ethernet (this is the gateway/firewall). I.e. the modem is doing the PPPoA but bridging the IP. This appears to be confounded by the PPP link having its remote endpoint not in the same network as the local endpoint. So when the ADSL modem responds to the DHCP request it supplies a local address in one network but has (and I assume provides via the DHCP "routers" attribute) a gateway which is in a completely different subnet. The result is that the interface on the Linux box (FWIW, Debian "sarge", using ISC dhclient) is configured with the correct local address but no default gateway. OTOH, if we use static configuration of the ethernet interface and set it up as a point-to-point ethernet link all works OK - but we're figuring this isn't really a cool long-term proposal as it obviously won't pick up any changes in the ISP-assigned attributes (e.g. gateway, DNS servers). Anyone know if either: (a) We're flogging a dead horse in trying to use DHCP like this? (b) There's a way of getting DHCP to configure pt-pt ethernet?
