Re: EdgeRouter Pro 8

Set up a firewall rule to prevent Inter-Interface routing. It's a little bit like preventing interVLAN routing, but the difference is that you are handling interfaces not VLANs. Make a new ruleset for each port (1-5) and set the direction to IN. Set default action to accept. Then set a rule to block access to other Subnets, give it a name, choose drop for actions. Under the destination tab, put in those IP Subnets (saperate them with a ',' ) you want to block.

Best regards,
Jack.
