@neik:
So if I am assigned 1.2.3.0/29 I would have the WAN as 1.2.3.6/32 and the LAN as 1.2.3.5/29, with the hosts on 1.2.3.1-1.2.3.4?
That does mean that the WAN is in the LAN subnet, even though it is a /32.
It's not equal though, with the WAN being only /32, it should be fine.
@neik:
Here in the UK we always, in my experience, just get a /29 or /28 block with one address in that block set automatically by the PPPoE connection. What would be "usual"?
The typical scenario with business class DSL in the US and most other places seems to be getting an IP assigned via PPPoE, and having the static subnet routed to that dynamically-assigned PPPoE IP. Sometimes, like with my AT&T Uverse at home, the modem must do the PPPoE and then my static /29 can either be assigned LAN-side of the modem, or routed to something with a private IP on the LAN.
It'd be nice to have unnumbered support at some point, not sure offhand if that's possible in mpd and FreeBSD.
