My current home network setup is something like this:
Until recently I had the truenet probe where the WR1043ND is now sitting. But the truenet probe is not gigE and the wifi doesn't seem all that reliable so I want to replace it with the WR1043ND, which I no longer use since getting the Fritzbox. The WR1043ND is running Gargoyle from when I used to run it with a half-bridged ADSL modem so I've left that on it, but I can reflash it to factory firmware if that's better.
Physically the Fritzbox and WR1043ND are at opposite ends of the house, so I have wifi turned on both of them and matching SSIDs and passwords, which I think should let wifi devices roam from one to the other, is this correct? this gives me full coverage of the whole house for wireless.
On the WR1043ND I have internet / WAN disabled and nothing plugged into the WAN port. Everything is using the gigE ports. Effectively I just want to use it as an access point / switch.
DHCP is off on both Fritzbox and WR1043ND and handled by the Amahi home server.
With everything setup like this I haven't noticed issues, but I've only just recently done it and am also curious.... so my questions:
1) Will this setup result in double NAT for the devices connecting to the WR1043ND?
2) If so what are the options for avoiding this?
3) Are there better ways to connect everything? (Preferably without buying anything new or additional wiring ;-) )
