Okay this might be a stupid question, but say I run Apache on my HP-UX machine to server a basic website. Can I then somehow tell Apache to use a specific Ethernet port, keeping all other traffic to another port?

I hope my PCIe NVME adapters arrive before Christmas. I bought them for one of my dual POWER9 workstations - it's been collecting dust for a while but I want to set it up again. Going to try FreeBSD, and hope that it supports the AMD Radeon Pro w5500 I bought for it. It's going to be a modern-ish UNIX workstation.
