I am doing something sort of similar ... use a routing protocol and set the metrics to make the LAN more attractive so it will get used over the wifi. Use dhcp to update dns.
I was using ospf (quagga), dns and ISC dhcp which auto-updates bind. This is "transparent" to the the hosts, is a pain to set up but then just works. Pinning addresses makes like life very difficult though as dhcp wont update dns so Ive gone back to manually setting up the dns side for some hosts :( BillK On 23/05/13 02:52, Michael Orlitzky wrote: > On 05/22/13 14:30, Samuraiii wrote: >> I'm sorry for mistake the subnet mask for both spaces IS 255.255.255.0. >> so it is not overlapping at all. >> I apologise for my mistake in notation. >> still this is not (mainly) problem with routing but problem with >> assigning name to address. >> If I had superfast internet connection I would not mind and just use vpn >> address space. >> So basically i need to assign lan address to computer (laptop) which is >> in same location (LAN) as other machines.
