Hello. I'm new here and new to nftables. Although familiar with iptables and networking. Anyways, what I'm trying to do is take a stream of traffic and send it to another mac on a linux bridge. The stream of traffic is the output from a switch mirror port coming into the linux bridge via one interface. I'd need to keep the IP's unchanged. I also need to SNAT the source mac....because the switch generating these mirrored packets is also plumbed into the linux bridge via another interface. I know. I know I sound like a crazy person. I believe or not have valid reasons for doing this and can't really talk about those. I'm going to try a ascii topo switch-----------------eno1-----br0 switchmirrorport----eno0-----br0 TL;DR I need to completely change the MACs on duplicate packets entering the same linux bridge on a different interface. Destination MAC is specific. Source MAC could be anything. Yes I know I'm insane Sorry forgot to mention I tried this with ebtables and could get the DNAT working but, could never seem to get the SNAT to work on those DNAT'd packets -- This email and any relevant attachments may include confidential and/or proprietary information.
