Is it possible to run a DHCP server on the HDR on demand? This would make it easy to set up ad-hoc point-to-point network access if required for maintenance purposes.
A different make of router - one which is completely configurable - and which doesn't have a modem built in. PPPoE service for internet now terminates on that router rather than the old modem(/router). It also has wireless built in and a gigabit switch. It does guest wireless, VPNs and VLANs as well (and that's just scratching the surface). I have 3 DHCP servers running on it, as there are 3 subnets configured! All in a nice plastic case . But not for amateurs/typical domestic use - you need some degree of clue about networking.May I ask what device now handles the DHCP service within your network? I am assuming that something must allocate IP addresses for all the other devices, or have you gone with some other configuration?
