Context: I just moved and still have to wait a while until I get an internet connection from my provider. In the meanwhile, my neighbor allows me to use his WLAN.
Issue: Many of my network devices (e.g. NAS) are only connected via LAN. Is there any way, I can use a WLAN router (e.g. with DD-WRT) to route traffic from my LAN to the WLAN?
Essentially what I'm looking for is a way to simply use the internet provided by my neighbor as the "uplink" - but have my own network infrastructure. Thus, the WLAN router would have to route the other way, i.e. forward/NAT everything coming from the LAN ports to the WLAN.
