Folks, I'm about to make a change in my external networking setup. I have 5 public IPs from Verizon FIOS and all 5 are coming into an OpenBSD 6.3 (shortly to be 6.4) box using pf and NAT. I would like to have four of the IPs continue to come into the OpenBSD box but pass through the fifth IP to another device without NAT. What would be the best way to do this? I have an extra physical ethernet port on my OpenBSD box so it's no problem to hook up an additional cable between the two.
Really horrible diagram here: https://drive.google.com/file/d/1vD7lLAXPfhmHtU8b60KGeHiAgb3k1Pa2/view?usp=sharing Would I need to bridge em0 and em2? Or is there a better way to think about how to approach the problem? --Paul
