I have a Linux network set up with three sub networks 192.168.1.0 (chaos), 192.168.3.0 (chaos-hs), and 192.168.5.0 (ute-netz) with three machines casimir, ute, raspberry, a nas server nas and a router speedport:
192.168.1.1 casimir.chaos (serves as gateway for all local machines)
192.168.1.61 speedport.chaos (internet router)
192.168.3.1 casimir-hs.chaos-hs (dhcp server for chaos-hs and chao
