Your network device's (commonly referred to as a "router") has an internal network. The internal network connects the internal physical(=hardware):

  • switch
  • wireless access point

with the:

Via the user interface you can modify how the hardware is logically interconnected with your software services. It is easy to lock yourself out of your network device and if/when you do, the first thing to do is to restart the device, wait for the PC ip settings and check if they are ok, because it might just be a device service that need to be restarted. If that does not work, you need to restore the firmware defaults. The software services are serviced by the network processor (ARM, MIPS...). Please note that the possibilities are limited by the software implementation and hardware.

List of non-exhaustive internal software services:

The software network services is connected by you, to physical or logical network interface. The interfaces might be a:

  • physical interfaces might be labelled eth0, eth1...
  • logical might be a bridge (=switch) labelled br0, br1...
  • logical vlan labelled vlan0, vlan1....

and maybe:

The default internal device networks in a non-802.11n network device - specifically the default configuration of a DD-WRT V23-SP2 firmware on a Linksys WRT54G v2. In a network device containing a 802.11n wireless access point the internal numbering of ports, bridges and vlans are different.
