Internal device network
From DD-WRT Wiki
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:
- network processors default internal device network and services.
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:
- Network traffic services:
- OSI layer 2 interconnection - ethernet address routing; bridge (ca.= software switch)
- OSI layer 3 interconnection - ip address routing; a software router
- OSI layer 2-7 moderation, ethernet transparent/bridging firewall, OSI layer 2-7 firewall
- OSI layer 3-7 moderation; common ip firewall, OSI layer 3-7 firewall
- Quality of Service
- Category:NAT
- Transparent web proxy
- (Inter)network client or server services:
- Network related server services:
- Management server services:
- Other server 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:
- teql0 - load sharing device I believe this is used for the "Link Aggregation on Ports 3 & 4" option on the Setup/Vlans page.
- imq0,1 - QOS device or IMQ Device
