Hi,
Sorry for bringing up such an old topic, but I've encountered the same problem. However, it seems like it's not the software version that causes the difference. I have several RB411's and RB433's running 5.6 and 5.16 working as outdoor wireless hotspots.
I'm using the rule:
/ip firewall filter
add action=log chain=forward comment="" connection-state=new \
disabled=no log-prefix="" protocol=tcp
to log connections. On RB411 and RB433 the src-mac field is logged.
Recently I've developed a RB750 (software version 5.6) to work as a hotspot router with a couple of indoor Linksys wireless AP's. The AP's are connected to the local interfaces of the RB750. And unfortunately the 750 doesn't log the src-mac field, only the inbound and outbound interfaces.
I'm wondering if it's the hardware version, that causes the difference, or is it the network configuration. Can anyone give me a hint?
Thanks,
Jacek
