@bpwl: Thank you for describing the setup. The only additional thing is I dont want LAN2 to have communication with LAN1
@anav: Thank you and yes I'd like devices connected to AP to be able to talk to each other but not to devices connected to the router itself. I'd rather AP just go straight to WAN.
I pasted the full config as you requested. Please let me know the best way to achieve my objective:
1- shield and protect router from attacks/unauth access
2- shield devices wired to router from WAN but allow them to talk to each other (except AP)
3- provide WAN access only to AP and devices connected to it.
Side note: AP (old Linksys router) has its own DHCP and provides its own IP to devices connected to it wirelessly.
