I hope this will be easy for someone to help me with. I have a router in a normal configuration 192.168.8.1 connected to conventional ISP. On this router is a samba server add-on running with non-protected data but I don't want my guests getting into the data. I am going to add a secondary router, 192.168.9.1 for my guests to get Internet access that has the secondary guest router WAN jack plugged into the LAN jack of my main router. Is there a line command to block guests that have wifi password for router 2 from accessing the server on 192.168.8.1?. So the gateway for secondary router 192.168.9.1 will be the primary router 192.168.8.1. Can I add a firewall command on block everyone on the secondary 192.168.9.1 router frrom accessing the samba server on 192.168.8.1 without also blocking the gateway part of the 192.168.8.1 router/server combo, or do I have to now configure all my appliances that access the samba server with log-in credentials for the share? (I don't want the passwords really for the primary network wireless, only for the guest wireless.) Thanks!
you should probably set a static IP for the WAN port MAC address, of the guest router,
then create a rule that will block traffic to the lan zone from that IP.
