Hello to evreyone,
I need help to help configure my router,,here is my situation
lan1 -> my ISP modem/router IP adress 192.168.1.x, 4PC (dhcp) withe shared folder, net printer and net scanner.
lan2 -> OpenWrt 18.06.9 router IP adress 192.168.10.y, other 7 devices (dhcp)
router 2 is connected (wan port) to lan port of router1, default config every thing is ok both works fine (lan and internet).
now please I need to know how to configur my router2(OpenWrt 18) to separate lan1 from lan2, no tarffic, no ping, no discovering,no sharing nothing at all... but lan2 can see lan1 especially the printer and the shared folder.
I have tried many configurations... not working! so please if anyone can tel me step by step how to configur the firewall I'll appreciate it a lot.
Thanks in advance
Samy
Actually the default OpenWrt configuration works fine for your needs. The devices connected to the lan interface of OpenWrt are able to access the lan of the ISP router and the internet, while anything connected on the wan interface of the OpenWrt router is not allowed to access the lan of OpenWrt.
