Ok, i'm migrating a flat network and using a pfsense as firewall.
i have a 3 interfaces box, one for wan, two for "lan".
For now i'm using both lans in the same subnet, with same ip. I do assign both ports (interfaces) the same IP. I do it to make easier the network configuration. The DHCP scope, for instance, provides one gateway for all hosts on my network. So it works like a charm, the problem is that in the end, this two ports are working like a hub. So the solution would be to enable "bridging" in both interfaces, right? But with bridging, can i still using one IP to both interfaces? Or should i create different subnets and assign different ips to both interfaces and keep both port in different subnets? The problem with this option is that it brings an undesirable complexity.
@jimp:
Then you bridge the interfaces together, not assign them IPs in the same subnet.
