Your network device (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 each other and with your software services.

Note: It is easy to lock yourself out of your network device and if/when that happens (use the waiting time checking the PC's ip settings - try release/renew the dhcp lease if not ok):
  • First: Wait some minutes - it might just be a temporary glitz.
  • Second: Try to restart the device, because it might just be a device service that need to be restarted.
  • Last resort: Restore to the firmware defaults by resetting the device.

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.
