Hi guys, Two questions based on the below setup: 3 WRT54G's all running DDWRT with DNSMasq and STP enabled. #1 WRT54G with QoS enabled resolves to the internet #2 WRT54G w/o QoS WAN port plugs into Port 1 on WRT54G #1 (This is my home wireless network) #3 WRT54G w/o QoS WAN port plugs into Port 2 on WRT54G #1 (this is the wireless network for the apartment I rent out). I have it setup this way so we cannot access eachothers computers on the local network. Each router has a firewall setup. 1: I am trying to understand STP and how best to use it. Should STP be enabled on all routers, or only the router that resolves to the internet? 2: What is the significance of DNSMasq? Thanks!
