Hi everyone,
I've been struggling with setting up my Routerboard so I can use it to Monitor Data traffic as well as using it for PPPOE.
I feel stupid for having to ask but the online manual does my head in and I've had no luck finding anything in the forums.

RouterBoard details are:
Model: 751G-2HnD
Current Firmware: 2.37
Upgrade Firmware: 2.36
I've attached a pic of the network layout.

Firstly I want to monitor the data traffic mostly to the Bartijn-Laptop but to all the systems connected if I can.

Second and the least important is using the RB for PPPOE.

Right now i have left it at the default settings but have secured the Wireless network.

Should I delete the current settings and start from scratch?
Is it worth using the RB for PPPOE or should I just leave it to my Modem?
Thanks
Chris
