I want to install additional Router between my USG4 and Internetrouter (Fritzbox). It is a School-Filter, his mision is to forbit access to rogue sites from PCs and mobile devices in the school.
My network looks this like:
ISP-> Fritzbox (192.168.178.0) ---> (DHCP) TimeForKids Filter (192.168.0.0) ----> (DHCP) USG4 (172.17.172.0) -> Switch
My PCs in school network are getting 172.17.172.0 addresses, but they are not capable to reach internet.
PING to public IPs (like Google) or PING to web-addresses are comming through, just websites in browser are not reachable.
How can I construct this to work?
