This is the WIP page for routing with ddwrt. Just to have something to start.


In general router works like this:

  apB--------apA-----Internet (WAN) connection
    |              |
clientB      clientA

Set the (Private_network private) subnetwork ip (sub)networks to e.g.:

  • apA 10.0.0.1/24 Short for: ( address 10.0.0.1 subnet 10.0.0.0 mask 255.255.255.0 = 24 left-to-right binary ones )
  • clientA 10.0.0.12/24 Short for: ( address 10.0.0.12 subnet 10.0.0.0 mask 255.255.255.0 )
  • apB 192.168.168.1/24 Short for: ( address 192.168.168.1 subnet 192.168.168.0 mask 255.255.255.0 )
  • clientB 192.168.168.15/24 Short for: ( address 192.168.168.15 subnet 192.168.168.0 mask 255.255.255.0 )

Routing (static) configurations:

  • tell clientA that apA is his default gateway (normally done through dhcp)
  • tell clientB that apB is his default gateway (normally done through dhcp)
  • tell apB that apA is his default gateway
  • tell apA that "WAN"-router is his default gateway
  • set the apB device to router mode
  • tell apA that requests to 192.168.168.0/24 will be routed through (apB) 192.168.168.1/24 (static route)

That's it!
