Hello I have a more difficult task that I would like to solve with OpenBSD and I would really appreciate any ideas if it is possible to achieve such.
I have: - one OpenBSD box with one Ethernet port - one big switch with multiple devices connected All switch ports are isolated by each other with one exception: - All ports can communicate with only one Ethernet port(let's say port 20) Now what i would like to achieve is to connect an Ethernet cable between OpenBSD box and port 20 of the switch, and make OpenBSD a transparent filtering hub. So I need OpenBSD box to be a transparent bridge and filter between clients of the switch. Can anybody suggest a point where I can think about? I was thinking initially to add the nic(em0) to veb0 then with link1 achieve L3 filtering but definitely I think I miss something important. I am open to research everything is needed for it but I miss a starting point and I would really appreciate any hint. Kind regards, Claudiu
