To explain your router: You have three actual hardware Ethernet MACs:
- The WAN (probably
- Internal (probably
- WIFI (probably
br0interface is a software bridging between
eth2. This way your wireless computer is on the same network as your wired computers. But it's not a real physical device but represents packets from either
eth2to the IP stack. The multiplexing is done in the driver for that interface.
As for the IP address discrepancy:
eth0does not actually act as your Internet. That's not how DSL from XXXXXXXX works.
eth0uses managed IP's to bring up a PPPoE session. So
ppp0will likely have your public IP address. Those packets get tunnled within the other set of IP's. That's a guess since I don't have XXXXXXXXX DSL though.
The thing with software, even embedded software these days is that there are so many layers of existing crap (that don't need to be there but skittish managers are loathe to remove things they don't grok) it's amazingly difficult to grasp the whole picture since there is often little rationale behind it.
That actually explains the behavior
I'm seeing on the router. So I can monitor the Intarweb traffic on
eth0, overall LAN
eth1 and the WiFi network via
