Hey all, I currently have a ISP provided router (which acts as DHCP and other functionality including the firewall and blocking by schedule etc), which connects to 2 24 port switches. Is it worth me getting a separate firewall device to restrict access to the home network? So i can restrict Wifi guests from getting on the home network, ie block from specific IP range onto home network via separate firewall? This is the firewall i had in mind which has separate connections for WANs etc. https://www.netgear.com/support/product/FVX538v2.aspx#docs Any thoughts would be greatly appreciated.
