I have been reading a ton of the different threads on here about how to properly route multiple IP addresses in an "additional IP" block (/28 block) through OPNSense. I'm going to post both here and on the OPNSense forum. So far, OVH keeps saying that I need to have a separate virtual MAC for each address separately, which then means that each one has to be mapped individually.
I was able to do this and see traffic coming in on one of the addresses, but nothing ever goes back out. Anything coming through the main WAN IP works just fine, but any of the additional IPs only allow inbound traffic. I also attempted to set up Outbound NAT and/or One-to-One NAT, since this particular IP will route to a single node on my network. Again, I see all of the traffic coming in and even passing to that node, but nothing ever makes it back out of the network.
Any ideas are really appreciated.
