I try to mirror the traffic on a pppoe network but receive nothing and --debug shows no error

15:50:57 root@OpenWrt ~ cat /etc/config/port-mirroring
#
#"target" defines the mirror target, it can be a local interface or a remote ip
#address. For openwrt routers, it shall be remote ip in most case.
#
#"source_ports" defines the mirrored interface, for example, "wlan0" will mirror#all wireless traffic. Multiple interfaces are supported(ie: "wlan0,eth0").
#

config 'port-mirroring'
    option 'target' '192.168.1.141'
    option 'source_ports' 'pppoe-pppoe'
    option 'filter' ''
    option 'protocol' 'TZSP'

I use wireshark on 192.168.1.141.If it mirrors these traffic,I should see ip packets which src ip is the ip from pppoe server.but I only get packets which src/dst ip is 192.168.1.x

sorry for my pool english

I think I know why it might not be working but I'll need more information to be sure:

1. What is the version number of port-mirroring you're using?
2. What is the brand, model, and revision number of your router?
3. What version of OpenWrt are you using?

By the way, your English is fine, no need to apologize.

I use port-mirroring_1.4.2_ar71xx which you offered in README.md router band is GL.iNet 6416 openwrt CC,download from https://downloads.openwrt.org/chaos_calmer/15.05/ar71xx/generic/openwrt-15.05-ar71xx-generic-gl-inet-6416A-v1-squashfs-sysupgrade.bin

I'm online, maybe you can use teamviewer or something to directly access my network,just tell me

Thanks for the quick response and you're using the right version of port-mirroring and OpenWrt with your router. I'm reviewing the code and it looks like a bug with port-mirroring. I don't think the original author anticipated using port-mirroring on a virtual network interface such as PPPoE which doesn't appear to have a MAC address or use address resolution protocol. I'll look into it this week but I can't guarantee when I'll be able to fix it.
