I have been fighting with a router for hours and haven't been able to accomplish what i want.
I have 10 computers with public ip- adresses,and need them to stay public. I Need to set rules so only these 10 computers Can talk to each other but no one else. I tried to put them. all on my lan side including cable towards inet.
I tried to get some rules for the län side but all rules seems to go from lan side to wan side. How Can i set these rules up? Do i need some other typen of box? I want like a switch with firewall functionallity.
